# Reflecting a Triangle in a Coordinate Plane

1. Draw a triangle with vertices at A(-3, 3) B(-2, -1), and C(-1,4). a. Reflect ABC in the y-axis to form A'B'C'

b. What is the relationship between the coordinates of the vertices of ﻿triangle ABC and those of triangle A'B'C'?

c. What do you observe about the side lengths and angle measures of the two angles?
