Question

Determine the coordinates of K, if KCDA is a Square! (4 marks)

Answer 1

In coordinate geometry, a square is similar to an ordinary square (See Square definition )with the addition that its position on the coordinate plane is known. Each of the four vertices (corners) have known coordinates. From these coordinates, various properties such as width, height etc can be found. 

It has all the same properties as a familiar square, such as:

All four sides are congruent

Opposite sides are parallel

The diagonals bisect each other at right angles

The diagonals are congruent
