Note: You must show all of your work, including use of the midpoint and distance formulae, to receive credit. Graph paper is recommended. You can print your own here. 1. A ABC have the following vertices A(-7, 4), B(11, 2), and C (-1, −6). ▲ DEF has vertices at the midpoints of AB, BC, and AC. Find the vertices of ▲ DEF. (3 points) 2. Find the perimeter of ▲ DEF to the nearest hundredth of a unit. (4 points) 3. Graph both triangles on the same Cartesian co-ordinate plane. (3 points)
