How many degrees is that angle?
b. Using the angle tool, measure by clicking the top intersection point then the midpoint then A. How many degrees is that angle?
c. To measure the length of the segments cut, hover over the angle tool, then click on the distance tool. Click on A then click on the midpoint. Click on B then click on the midpoint. What do you notice about the measures?
d. Given your measures above, why do you think the line segment you created is called a perpendicular bisector? (In other words what does [b][i]perpendicular[/i][/b] mean and what does [b][i]bisector[/i][/b] mean?)
We're going to measure the distance from points on the perpendicular bisector to A and B.
1. Use the measure distance length tool (under the angle icon) to measure the distance between the top intersection point and point A. Then measure the distance between the top intersection point and point B. What are the two distances?
2. Add 3 more points to line CD. Repeat the same process above, using the measure tool to measure the length of each new point to A and B. List each distance below.
Given above, finish the following sentence:[br][br]A point is on the perpendicular bisector of AB if the point is..
