Unit 1 Day 3: Apply Segment Addition Postulate
Directions on how to find the Distance tool to measure length between two points.
and the click on
. Second, click on point A and then on point B to find AB, the distance between both 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.
