Prove that the points A (-5, 4), B (-1, -2) and C (5, 2) are the vertices of an isosceles right-angled triangle. Find the coordinates of D so that ABCD is a square.
Solution:
Find the third vertex of a triangle if its two vertices are (-1, 4) and (5, 2) and the midpoint of one side is (0, 3).
Solution:
