Midpoint = (x1+x2 , y1+y2)
2 2
Triangle has 3 sides, so we'll compute midpoints of each side.
Side 1:
Adjoining vertices = (3,5) and (6,-4)
Midpoint = (3+6, 5+ -4)
2 2
MIdpoint = (9/2 , 1/2) for Side 1
Side 2:
Adjoining vertices: (6, -4) and (-1, 1)
Midpoint = (6+ -1 , -4 + 1)
2 2
Midpoint = (5/2 , -3/2) for Side 2
Side 3:
Adjoining vertices: (-1, 1) and (3, 5)
Midpoint = (-1 + 3 , 1 + 5)
2 2
Midpoint = (2/2 , 6/2)
Midpoint = (1 , 3) for Side 3
