Math Grade 5 Quadrilaterals

REMEMBER! A polygon is a closed figure that has three or more sides. Each side is a line segment, and the sides meet only at their endpoints. POLYGON NOT POLYGON

Types of Polygons Regular Polygon Irregular Polygon All sides equal Sides of different lengths All angles equal Angles of different measures

Quadrilaterals 4 sides 4 angles

Quadrilateral A polygon with 4 sides The sum of its angles is 360˚ We can use sides and angles to classify quadrilaterals.

Parallelogram Quadrilateral Opposite sides are parallel and equal Opposite angles are equal

Rhombus Quadrilateral Opposite sides are parallel and equal Opposite angles are equal 4 equal sides Which makes it a parallelogram

Rectangle Quadrilateral Opposite sides are parallel and equal Opposite angles are equal 4 equal angles each is 90˚ Which makes it a parallelogram

Square Quadrilateral Opposite sides are parallel and equal Which makes it a parallelogram Opposite angles are equal 4 equal sides 4 equal angles each is 90˚ Which makes it a rhombus Which makes it a rectangle

Trapezoid Quadrilateral ONLY ONE PAIR of opposite sides is parallel

Family of Quadrilaterals Quadrilateral Trapezoid Parallelogram The trapezoid does NOT belong to the family of parallelograms. Rectangle Rhombus Square
