Mark the points as A, B, C
A: (4, 4)
B: (3, 5)
C: (-1, -1)
Slope of AB = (5-4)/(3-4) = -1
Slope of BC = (3+1)/(5+1) = 2/3
Slope fo AC = (4+1)/(4+1) = 1
Two lines are perpendicular if the product of their slopes is -1
-1 × 1 = -1
AB is perpendicular to AC
ABC is a right-angled triangle with a right angle at A (4, 4)
