# Chapter 3: Basic Geometry TE - Enrichment

**Basic**Created by: CK-12

**Introduction**

This FlexBook® resource is designed to supplement the Basic Geometry FlexBook® textbook with enriching and extension activities. Mostly, the activities will cross into art, technology, architecture, and history. By definition, enrichment means to “enrich” or enhance something. The activities or problems included will enrich the lesson and add to the lesson without adding too much of a challenge. There will also be “challenging” problems that be separately identified. Like with the other FlexBook® resources, the activities and problems in this text are suggestions and designed to supplement a lesson. Pick and choose activities as you see fit.

In addition to the supplemental activities in this FlexBook® resource, see the Texas Instruments Geometry FlexBook® textbook. This book has activities that supplement some sections and are designed to utilize a graphing calculator. See http://www.ck12.org/flexbook/book/3783/ for the Teacher’s Edition and http://www.ck12.org/flexbook/book/3766/ for the Students’ Edition.
