Exploring and Classifying Polygons Lesson 15-5

Polygons A polygon is a closed figure whose sides are made up of straight line segments that do not cross.

Naming Polygons

Classifying Quadrilaterals Quadrilaterals are four-sided polygons. Trapezoids have exactly one pair of parallel lines.

Parallelograms have two pairs of parallel lines. There are three special kinds of parallelograms: A rectangle has four right angles. A rhombus has four congruent sides. A square has four right angles and four congruent sides.
