## Directions on how to find the Distance tool to measure length between two points.

## Activity: Find the Indicated Lengths.

This activity will count towards classroom participation and you will have 10 minutes.

## Applet #1: Use this applet to answer questions #1 - 5 below.

1. Use the and then the ** tools in the applet above **to find the indicated **lengths** below.
**a.) Find AB b.) Find BC c.) Find AC**

2. What do the lengths you found tell us about the relationship of those three points?

3. In question #1 you found the length AC by using the and tools in the applet. Is there another way to find length AC? Explain.

## Applet # 2: Use this applet to answer questions #4 and 5.

4. Find the lengths AB and BC using the **angle** and **distance (length) tools. **

5. Can you use the **Segment Addition Postulate** to find the length AC? **Explain**.
