Compare the perimeter of ^ABC to the perimeter of the triangle whose vertices are the midpoints of ^ABC

Question

A(-5,8)

B(-1,-3)

C(4,2)

Answer 1

From Talete's theorem (parallel lines .....), we can say that the perimeter is half of the triangle whose vertices are the midpoints of triangle ABC

So you can calculate the perimeter of ABC and than divide by 2
