PREPARED BY: ANUPAM BHALLA (Math Mistress) GGSSS,MS ROAD,ASR.
QUADRILATERALS A quadrilateral is a plane figure bounded by four straight lines. There are several familiar types of quadrilaterals. 1. SQUARE 2. RECTANGLE 3. PARALLELOGRAM 4. RHOMBUS 5. TRAPEZIUM 6. IRREGULAR QUADRILATERAL
SQUARE A square is a parallelogram whose angles are right angles and whose sides are of equal length.
RECTANGLE A rectangle is a parallelogram whose angles are all right angles.
PARALLELOGRAM Parallelograms are quadrilaterals that have opposite sides of equal length.
RHOMBUS A rhombus is a parallelogram (and therefore also a quadrilateral) whose sides are equal.
TRAPEZIUM Trapezium are quadrilaterals that have two parallel sides of unequal lengths.
Irregular quadrilateral . Irregular quadrilaterals have four unequal and nonparallel sides
