Question

Graph the figure A(-2,1), B(2,5), C(1,2). Reflect the triangle across the x-axis. Using A’, B’, and C’ to label the new points, what are the coordinates of the image (new figure)

Answer 1

• A'(-2, -1), B'(2, -5), C'(1, -2)

Explanation:

Given

• A(-2,1), B(2,5), C(1,2)

Reflection across x-axis rule

• (x, y) → (x, -y)

New points are

• A'(-2, -1), B'(2, -5), C'(1, -2)
