Coordinate Geometry Quadrilaterals

Introduction:

The coordinate geometry is also called a coordinate plane. It enables a plane in perpendicular axes : x and y in two-dimensional form. The horizontal direction indicates the x-axis while the vertical direction y-axis indicates of the plane. In these points are indicated by their positions along the x and y-axes.

Coordinate Proof and Quadrilaterals:

Proof: - Positioning a Square

Position and label a square with side’s n units long on the coordinate plane.

• Let A, B, C, and D be vertices of the square.
• Place A at the origin. As a result, AB is on the
  positive x-axis and AD is on the y-axis. Label
  the vertices A, B, C, and D.
• The y-coordinate of B is 0 because the vertex is
  on the x-axis. Since the side length is n,
  the x-coordinate is n.
• D is on the y-axis so the x-coordinate is 0.
  The y-coordinate is 0 + n or n.
• The x-coordinate of C is also n. The y-coordinate is
  0 + n or n because the side BC is n units long.
