## CHAPTER 7: TESSELLATIONS

**Lesson 2: Tessellating with Regular Polygons **

Use these interactive activities to encourage students to have fun on the Web while learning about tessellations. Students can try these activities on their own or in pairs.

**Goal**

Use angle relationships to identify regular polygons that tessellate.

**Builds Upon**

Student Book pages 289–292

**Instructions for Use**

**Regular Polygons** allows students to see some regular polygons that can tessellate and some that cannot and allows them to figure out why.

Read through the information about tessellating regular polygons. Write an explanation of why the shapes shown can or cannot tessellate. Hint: think about angle relationships.

**Regular Polygon Tessellations I** allows students to investigate why some regular polygons can tessellate and some cannot.
