What are Quadrilaterals?

 

The origin of the word “quadrilateral” is from the Latin words quadric meaning “a variant of four” and latus meaning “side”. A Quadrilateral is a figure formed by joining four points in order.

 

Properties of Quadrilaterals

 

1. Quadrilateral has exactly four SAV (Sides, Angles, and Vertices):

  • Sides (AB, BC, CD, AD)
  • Angles (∠A,∠B, ∠C, ∠D)
  • Vertices (A, B, C, D)

2. Sum of the angles of a quadrilateral is 360° (Angle Sum Property)
∠A + ∠B + ∠C + ∠D = 360°
