Question

Find the coordinates of the vertices after the reflection across the x axis and then across the y axis.

Answer 1

A'(2, -3), B'(-3, -4), C'(-2, 0)

Explanation:

Reflection across each of the axes is equivalent to reflection across their point of intersection, (0, 0). Such a reflection negates both the x- and y-coordinates of the original point.

A' = -A = -(-2, 3) = (2, -3)

B' = -B = -(3, 4) = (-3, -4)

C' = -C = -(2, 0) = (-2, 0)
