1 Polygons with four sides
Quadrilaterals Polygons with four sides

2 Types of Quadrilaterals
Square: Quadrilateral with four equal sides and four right angles (90 degrees) Indicates equal sides Box indicates 900 angle

3 Types of Quadrilaterals
Rectangle: Quadrilateral with two pairs of equal sides and four right angles (90 degrees) Indicates equal sides Box indicates 900 angle

4 Types of Quadrilaterals
Parallelogram: Quadrilateral with opposite sides that are parallel and of equal length and opposite angles are equal Indicates equal sides

5 Types of Quadrilaterals
Rhombus: Parallelogram with four equal sides and opposite angles equal Indicates equal sides

6 Types of Quadrilaterals
Trapezoid: Quadrilateral with one pair of parallel sides Parallel sides never meet.

7 Types of Quadrilaterals
Irregular shapes: Quadrilateral with no equal sides and no equal angles

8 Name the Quadrilaterals
1 3 2 irregular rhombus rectangle 5 6 4 parallelogram trapezoid square

9 Interior Angles Interior angles: An interior angle (or internal angle) is an angle formed by two sides of a simple polygon that share an endpoint Interior angles of a quadrilateral always equal 360 degrees
