Question

A) If 2 points on the rectangle are (a, b) and (c, d), then identify the two missing points on the rectangle?

b) How would you find the width of the rectangle, given only the information above?

Answer 1

Let us write vertices of the given rectangle are PQRS.

Where Q is (c,d) and S is (a,b).

a) Now, we need to find the coordinates of P and R points.

x-coordinate for P is a and y-coordinate of P is d.

Therefore P is (a,d).

On the same way, x-coordinate for R is c and y-coordinate of R is b.

Therefore R is (d,b).

b) Width of the rectangle is difference of y-coordinates of P and S points.

Therefore, width = b - d.
