# Chapter 6: Geometry and Transformations

**Basic**Created by: CK-12

## Introduction

In Math 8, the learning content is divided into Concepts. Each Concept is whole and complete providing focused learning on an indicated objective. Real-world Concepts involve the student in the learning objective of each Concept. Students are given opportunities to practice skills through real-world situations, examples, guided practice and independent practice sections. There are video links provided for Concept connections with technology. In this Chapter, students will engage with content that is related to geometry and transformations. Concepts will include identifying angle pairs, adjacent and vertical angles, measures of angle pairs, classifying and measuring triangles, classifying and measuring quadrilaterals, identifying polygons, methods for proving triangle congruence, transformations, similarity and dilations.
