Hierarchy of Quadrilaterals Day 13

Day 13 Math Review Math Review Quiz Day

Objectives Classify polygons based on their sides and angles. Find and use the measures of interior and exterior angles of polygons. Use properties of parallelograms to solve problems. Use properties of rectangles, rhombuses, squares, kites, and trapezoids to solve problems.

Vocabulary side of a polygon vertex of a polygon diagonal regular polygon concave convex parallelogram rectangle rhombus square kite trapezoid base of a trapezoid leg of a trapezoid base angle of a trapezoid isosceles trapezoid midsegment of a trapezoid

Each segment that forms a polygon is a side of the polygon. The common endpoint of two sides is a vertex of the polygon. A segment that connects any two nonconsecutive vertices is a diagonal.

All the sides are congruent in an equilateral polygon. All the angles are congruent in an equiangular polygon. A regular polygon is one that is both equilateral and equiangular. If a polygon is not regular, it is called irregular. A polygon is concave if any part of a diagonal contains points in the exterior of the polygon. If no diagonal contains points in the exterior, then the polygon is convex. A regular polygon is always convex.

Activity For each shape that appears, write down everything you know about it. (pages 45-50) You may have to measure. Share with the class what you came up with. Arrange the pieces so that they all connect together. Put on poster paper. Present
