Activity In this activity, you will use the GeoGebra geometry tool to explore the properties of line segments and angles. Open GeoGebra, and then complete each step below. If you need help, follow these instructions for using GeoGebra. Question 1 Plot three points on the coordinate plane and label them A, B, and C. (Be sure that all three points do not lie in a straight line.) Now join the points two at a time using straight paths. How many unique straight paths can you make through the points? Which geometric figure is formed?
