Quadrilaterals

Slide 1 : QUADRILATERAL A quadrilateral is a four sided polygon with four angles

Slide 2 : QUADRILATERALS RECTANGLE SQUARE RHOMBUS TRAPEZOID

Slide 3 : RECTANGLE A rectangle is a four sided closed figure in which every angle is a right angle Show equal sides Opposite sides are parallel and equal

Slide 4 : SQUARE A square has equal sides and every angle is a right angle Also opposite sides are parallel.

Slide 5 : RHOMBUS A rhombus is a four-sided closed figure in which all sides are equal in length. Opposite sides are parallel Opposite angles are equal. The diagonals of a rhombus bisect each other at right angles.

Slide 6 : TRAPEZOID One pair of opposite sides parallel
