Types of Quadrilaterals - Part 2

Trapezium

Types of Quadrilaterals - Part 3

One pair of parallel sides

AB ∥ CD

 

Parallelogram

Types of Quadrilaterals - Part 4

Opposite sides are parallel

  • AB ∥ CD
  • AD ∥ BC

 Opposite sides are equal

  • AB = CD
  • AD = BC

 

Rhombus

Types of Quadrilaterals - Part 5

Parallelogram with all sides equal

So,

  • AB ∥ CD & AD ∥ BC
  • AB = BC = CD = AD

 

Rectangle

Types of Quadrilaterals - Part 6

Parallelogram with opposite sides equal & all 4 angles 90°

So,

  • AB ∥ CD & AD ∥ BC
  • AB = CD & AD = BC
  • ∠A = ∠B = ∠C = ∠D = 90°

 

Square

Types of Quadrilaterals - Part 7

Parallelogram with all sides equal & all 4 angles 90°

So,

  • AB ∥ CD & AD ∥ BC
  • AB = BC = CD = AD
  • ∠A = ∠B = ∠C = ∠D = 90°
