## CHAPTER 7: 2-D GEOMETRY

**Lesson 4: Rotations **

Use these interactive activities to encourage students to have fun on the Web while learning about 2-D geometry. Students can try these activities on their own or in pairs.

**Goal**

Perform and describe rotations in all four quadrants of a Cartesian plane.

**Builds Upon**

Student Book pages 296–299

**Instructions for Use**

**Measuring Turns** allows students to predict the outcome of various rotations of different figures.

Read the rotation questions and predict what each figure would look like after the rotation described. You get 10 points for every correct prediction.
