Given two adjacent vertices, (x1, y1) and (x2, y2), for a square, find the other two vertices. (Derive formulas for the coordinates of those vertices, in terms of x1, x2, y1 and y2.
Given: (x1, y1) and (x2, y2)
Let's consider a square having adjacent vertices (x1, y1) and (x2, y2)
From the above square, we conclude that x1 = x4 x2 = x3 y1 = y2 y3 = y4 Side of the square = (x2 - x1) (x3, y3) = (x2, y2 + (x2 - x1)) OR (x3, y3) = (x2, y1 + (x2 - x1)) (Because y1 = y2) (x4, y4) = (x1, y1 + (x2 - x1)) OR (x4, y4) = (x1, y2 + (x2 - x1)) (Because y2 = y1)
