Question

Find the coordinates of the reflection: B (5, 4) is reflected over the line x=1
B’=?
Question 10 options:

a) (6, 4)

b) (6, 5)

c) (-3, 4)

d) (4, 4)

Answer 1

use the same formula but in this case since x=1 is given so x= 2times 1-x ,y be the answer

Answer 2

sorry for delay .some technical prob occured !

Answer 3

oh its ok i just don't understand the formula i've never done this before

Answer 4

this one also c !

Answer 5

ok thanks :DD

Answer 6

ok i will give u table so that it'll be easier for u to do other too ok !

Answer 7

and i have a small question but what is an isometry?

Answer 8

ok

Answer 9

well isometries are reflection , rotation , translation all thse stuffs

Answer 10

yes i know that but isnt it a shape that is the same that gets bigger or smaller?

Answer 11

but streach and shrink are notisometries

Answer 12

oh

Answer 13

yah !

Answer 14

ok so if it stays the same as the original shape its not an isometry?

Answer 15

for the reflection abt x axis
\[x^l=x , y^l= -y \]

Answer 16

for the reflection abt y axis \[x^l= -x , y^l=y \]

Answer 17

for the reflection abt y=x \[x^l=x, y^l=y\]

Answer 18

for the reflection abt y=-x \[x^l=-x, y^l=-y\]

Answer 19

for the reflection abt x=h where h=1,2,3......\[x^l=2h-x , y^l=y\]

Answer 20

for the reflection abt y=k where k=1,2,3.....
\[x^l=x , y^l= 2k-y \]

Answer 21

now remember few things then you can easily solve others

Answer 22

reflection siply means mirror images ! like
