Introduction to Geometry


After discussing basic geometric terms, the chapter presents information on pairs of angles, quadrilaterals, and triangles. The students study the  classification of geometric figures as well as perimeter and area formulas. The chapter concludes by exploring some basic triangle theorems including the Pythagorean Theorem.

What you can expect to learn
