Overview

Special types of quadrilaterals are shapes with special side, angle, and diagonal properties. A quadrilateral is a closed polygon with four sides, and the sum of its interior angles is 360°. The chapter covers trapezium, isosceles trapezium, parallelogram, rectangle, rhombus, square, and kite, along

Key Concepts

A quadrilateral is a closed polygon

A quadrilateral is a closed polygon with four sides, four vertices, four angles, and two diagonals. The sum of its interior angles is 360°.

A trapezium is a quadrilateral

A trapezium is a quadrilateral in which one pair of opposite sides are parallel and the other two sides are non-parallel. If the non-parallel sides ar

In an isosceles trapezium

In an isosceles trapezium, the non-parallel sides are equal. The base angles are equal: angle A equals angle B and angle C equals angle D. Its diagona

A parallelogram is a quadrilateral

A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel. In a parallelogram, opposite sides are equal, opposite angles a

A quadrilateral is a parallelogram if

A quadrilateral is a parallelogram if opposite sides are parallel, opposite sides are equal, opposite angles are equal, diagonals bisect each other, o

Learning Objectives

  • Identify different special quadrilaterals from their side and angle properties.
  • Use diagonal properties to prove whether a quadrilateral is a parallelogram, rectangle, rhombus, or square.
  • Apply angle-sum and parallel-line properties to solve simple problems.
  • Understand how special quadrilaterals are related to one another.
  • Use congruence ideas to prove results about diagonals and sides.
