Think about it ...

Question

Julie says that a rotation of 180° around the origin is the same as the reflection in the x-axis followed by a reflection in the y-axis. Is Julie correct? Justify your answer and be sure to include a diagram.

I just wanna know does Julie correct or not. And why.

Answer 1

start with general point (x,y)
reflection in the x-axis ----> (x, -y)
then a reflection in the y-axis ---->(-x,-y)

reflection in the origin: (x,y) ----> (-x,-y)

Yup, Julie is correct.

Answer 2

Thank you very much ^^
