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?
