Answer:

  • No

Step-by-step explanation:

You may find the slopes of the segments EG and FG, the shorter sides of the triangle EFG.

Perpendicular lines have negative-reciprocal slopes.

  • m(EG) = (-3 - 7)/(-6 - (-2)) = -10/-4 = 5/2
  • m(FG) = (-3 - (-8))/(-6 - 7) = 5/-13 = -5/13

The product of the slopes should be -1:

  • 5/2*(-5/13) = - 25/26 ≠ -1

So the answer is No
