REFLEKSI (Pencerminan) - Cara menentukan bayangan titik

Hi Okay Assalamualaikum warahmatullahi

wabarakatuh meet again with

our channel great mathematics well in our video

this time we will try to discuss the

material that is about reflection or

mirroring that is about how

to determine the shadow of a point this

is a mathematics material for kindergarten junior high school

and also mathematics material for

high school level can before we continue don't

forget to like subscribe comment and share

our video hopefully the video is useful

and hopefully it can be a charity

for us later and now let

's just discuss the example questions

but before that it's good for us to

understand first some

important materials to make it easier for us to

answer questions about this reflection,

namely as follows we have

summarized it into a table form

usually here there is a form of a

reflection okay then we are given a

point usually kebab then

Khan the point is on the right side of this

Well to make it easier for us to

understand the summary of this material let's just

discuss the example questions Determine

the shadow of the point if the first question

finding a 3.5 is reflected on the

x-axis the second question point B 4.2

is reflected on the y-axis the

third question point c 2.375 is reflected

to the origin 0,0 and so on

this time we have 7 Make a question and that

God willing we will answer one by one

until you can later now

let's start to discuss the

first question first the point

advrcntr3.dll x-axis pay attention to the

steps in this work it is very

easy remember once again

To make it easier for us to answer

questions about reflection of course you

have to really understand the material that

has been camera kuntadi in the form of a

table earlier Well here it is if we have

mastered this God willing

we can easily answer questions about reflection

earlier no for the first one we

were given a point a 3,5 then

reflected on the x-axis

Pay attention to the table here reflection on the

x-axis if for example we are given a

point a comma b then the shape of the shadow of

the point is a woman FB the front number

remains the root behind it is associated with

negative previously positive b then it

changes to negative

Oh so it is with this time then the

shape of the shadow after being reflected

on the x-axis becomes a accent

in brackets once again Pay attention to the

front number remains a-rank kablak

gangnya multiplied by negative previously

positive B then the shadow changes to

negative B well so it is with The

front id point remains 3.4 Now the

last number changes to negative, it was

positive before, where now it changes

to negative 5 Now this is the correct answer

to our first question

Yes, it's not very easy

of course Ok, continue he understands better

Now we will go into the second river,

pay attention to the second point B 4.2

reflected on the y-axis, here are the

display steps, point B

4.2 is negative two, then it is reflected

on the y-axis, pay attention to the reflection of

your y-axis, we are like this, point a

comma b, then the shape of the shadow after

being reflected on the y-axis is there, it

becomes negative A5B, the front number

is multiplied by negative, the

back number here he still pays attention to

the shadow of point B, this B accent, the

front number is multiplied by negative once

again, Pay attention to the front number multiplied

by negative, it was positive exactly

multiplied by negative, it becomes negative 4, now the

back number is still

Srikandi here, but then here

it is also negative two Now this is the

correct answer to our

second question, it is very easy, you certainly continue

he understands better, we go into the third question,

point c 2.5 is reflected

on the origin 0.0 three Our point is

at 2.375 then it is reflected to the

origin point note the reflection of the

origin point 0.0 if we are given a point a

comma b then the shape of the shadow is

negative acoma negative all these number points

are associated with a negative sign

previously positive-positive b then the shape of

the shadow is negative negative B

likewise Relax the third woman is point

c then the shape of the shadow is C accent

remember all the numbers here are multiplied

by the land

Hi then the shape of the number pay attention

once again positive 2 then the shadow is

negative two then comma previously negative 5

then right the service here is

positive 5 remember all the numbers here

are multiplied by a negative sign positive 2

times negative becomes negative 2 negative

5 in you multiplied by negative the

result is positive this is the

answer form of the third example dear continue

again so that we really understand we

enter the fourth question negative meet point

7.2 is reflected to the line

y = x okay pay attention to point D negative 7.2

is reflected to the line y = x

reflection of the line y = x if we are given a

point a comma b then the shape of the shadow

is becom aa aa

just swap the position previously AB then the

shape the danger of customs Likewise with the

point at us this time the

shadow form is the absent which

was previously negative 7.2 then the

shadow form gives it now it is

2.5 egat yv7 well this is how

to reach the 4th very easy

of course Ok continue he understands better

now we go into the fifth like

point e 5.4 is reflected on the line

y is equal to negative X make sure point e

So 5.45 lu is reflected on the

line y = x line y = min x if we

are blessed with point a comma b then the

shadow form is negative become negative

a

Mbok Ade she swapped positions means that

previously it was finished now it changed to customs Then

after that it was multiplied by the

negative sign previously positive AB now

it changed to negative B negative a & b that is

also with the TNI point according to the fifth

shadow form after being reflected

on the line y = min x namely the number of

X accents in brackets starting from the first he

swapped positions previously 54 now it changed

to 45 after that it was multiplied by the

negative sign so now it becomes

replaced by V4 okay comma negative 5 Well this is the

correct answer from Our question

number five continues now we go to the

other six points f 2.33 reflected

on the line x = 3 Y

brother the solution steps mix

point FT at 2.33 then reflected

reflect on the line x = 3

this calf x = h if we are near point a comma

b then the shape of the shadow is the

front number note for the slightly different

Club it changes to 2H minus a

if HK the value of our hadith al this time

is three Yes the dream is still okay Tadika

then the shape of the shadow is F accent

in brackets the front number note the

change this front number is two [ __ ]

minus a-ha this if we can this time

three steps so it is two when

the package is twice Abadi 2 times three

Then it is explained

Hi this current value is like this laiya

here we are two batti2 times three which is here

subtracted by two which is here comma

then the purchase number make sure he remains

this calf he remains negative 3 continue F

accent in brackets two times three the

result is 6 then 6 minus 2 the result is

4.3 the back is still negative 3

Well this is the answer to

our last sixth question This is

the last question number 7

negative Gis point 1.7 is reflected on the

line y = 4 but make sure the height of

negative 1 point seven is reflected

on the line y = 4 line y = if

for our formula this time pay attention to

the changes

Hi if for example we are blessed with point

a comma b then the shape of the shadow

pay attention to A5 the front number remains Aa

then the back number changes previously

by now changes to two chalk b & k

here for our prayer this time that is

the value 4D pay attention to the shadow gi

then the shadow is G accent will be

in front once again Pay attention to the

front number remains if here the

front number is negative one then the

back number just changes previously B

now changes to two less b

the value of this Village Head is four so pay

attention once again two here okay

I multiplied by four here

then described with BB Here in

others 7 George in ASEAN in brackets

negative one

Mbak comma 2 times 4 only eight then

8067 the result is one and this is

how to solve questions

about reflection or shadow of a

point that's our short tutorial

hopefully the video is useful More and

less we apologize we close with Peace be

upon you, and Allah's mercy and blessings
