Quadrilaterals Lesson 11 – 5

Quadrilateral Def: a 4 sided polygon. or ‘ a figure with 4 sides and 4 angles’ **The SUM of the 4 angles must equal 360º** Examples: square, rectangle, rhombus, trapezoid, parallelogram

Parallelogram Def: a quadrilateral with both pairs of opposite sides congruent and parallel. Examples: square, rectangle, rhombus,

Square Def: a parallelogram with 4 right angles and 4 congruent sides

Rectangle Def: a parallelogram with 4 right angles Examples: square, or rectangle

Rhombus Def: a parallelogram with 4 congruent sides Examples: square, or rhombus

Trapezoid Def: a quadrilateral with only 1 pair of parallel sides. *none of the sides have to be congruent* Examples:

Sometimes, Always, or Never? A rectangle is a quadrilateral A rhombus is a square A square is a trapezoid A rectangle is a square A square is a rectangle A square is a rhombus A trapezoid is a parallelogram

Sometimes, Always, or Never? A trapezoid is a quadrilateral A trapezoid can have three right angles A parallelogram is a square A rhombus is a rectangle A quadrilateral is a trapezoid The sum of a trapezoid’s angles = 345º
