1. find the side lengths of a triangle with the given vertices.
part i: graph and label a triangle on the coordinate grid below.
a. plot and connect these points: a (1, -3), b (3,-1), c (5,-3). (3 points)
b. using the grid, find the distance between a and c. identify this on your graph. (1 point)
c. angle b is a right angle. identify this on the graph. (1 point)
d. angles a and chave the same measure. using what you know about the sum of angles in a
triangle, find the measure of angles a and cand label these on your graph. (2 points)
