Area of Regular Polygons and Quadrilaterals Lesson

Description

This resource practices finding areas of squares, rectangles, parallelograms, triangles, rhombi, trapezoids and regular polygons. Students should be familiar with most of the formulas, so as an extension, students practice finding missing sides when the area is given. Circle problems and perimeter problems are also thrown in on a few worksheets.

Before learning the formula for area of regular polygons, students will learn the formulas for sum of the interior angles of polygons, finding one interior angle of a regular polygon, and finding the sum of the exterior angles of a polygon. Students are expected to apply their knowledge of Pythagorean Theorem and Special Right Triangles on certain area problems.

This lesson has 3 parts:

• Review of area of basic 2-d figures and finding area of a composite figure.
• Finding the sum of the interior and exterior angles of a polygon and finding one interior angle of a regular polygon.
• Finding the area of regular polygons.

All types of regular polygons are visited, but most of the focus is on hexagons, pentagons and octagons. This resource contains a lesson plan, notes, practice pages and a two version quiz.
