Part I: Graph and label a triangle on the coordinate grid below. 1. Plot and connect these points: A (1,-3), B (3, -1), C (5,-3) (3 points)
2. Using the grid, find the distance between A and C. Identify this on your graph (1 point)
3. Angle B is a right angle. Identify this on the graph. (1 point)
4. Angles A and C have the same measure. Using what you know about the sum of angles in a triangle, find the measure of
angles A and C and label these on your graph. (2 points)
