Question

How would I do this and find the coordinate points?

Answer 1

If the point (x, y) is reflected across the x-axis, then its image is (x, -y)

If the point (x, y) is reflected across the y-axis, then its image is (-x, y)

Since triangle ABC is reflected across the x-axis, then across the y-axis, then we will change the signs of the x-coordinates and the y-coordinates of its vertices

A = (-5, -1), then

A' = (-5, 1)

A'' = (5, 1)

B = (-3, -5), then

B' = (-3, 5)

B'' = (3, 5)

C = (-1, -1), then

C' =(-1, 1)

C'' = (1, 1)
