Question

Name the translation image of ABC after a reflection across line t and then a reflection across line r.
A. UVW
B. LMN
C. XYZ
D. DEF

Answer 1

- so what you think about first - when you try reflecting an line for example what will get ?
so one same line - yes ?
- so than try reflecting these lines of a triangle how you think what will get ?
- i think same triangle
so than you check the reflection image after line ,,t" how you think what triangle will be same with reflected triangle ?

- the nearest point of triangle to t need being nearest point to line t in case of reflection image too
so using this property the answer to first point will be triangle OPQ

do you understand it why ?

so the answer on second question because the point Q is the farthest point to line r so in case of reflection image need being the farthest point too
- using these above wrote will be triangle UVW

hope these will help you understanding all right easy

Answer 2

thank you, it was A.
