**Activity 1**
As a class or with the students in pairs, go to one of the following geogebra sites:
https://www.geogebra.org/m/tNsdcxTB
https://www.geogebra.org/b/rSuyACJC#material/cywM9VXZ
As you or the students check each box of angle pairs and move the points around, take note of what happens to the angle measurements. What conclusions can be drawn from these angle pair measurements? Congruent? Supplementary? Complementary?
**Activity 2**
Have students go to https://www.geogebra.org/graphing and follow the directions below. (For information on geogebra tools: https://wiki.geogebra.org/en/Graphics_Tools)
STUDENT DIRECTIONS
Click on the point tool icon and choose the line tool. Insert 1 line by click on two points.
Click on the line tool icon and select parallel line. Click on the line you just made and insert a parallel line anywhere on the graph.
Click on the point tool icon again (the line tool should already be chosen). Insert your transversal by clicking on points B and C.
Click on the measurement tool icon and choose angle measure. Click on points A, B, and C to find the measure of one angle.
Click on the special objects tool icon and choose the text (abc) tool. Students should use their given angle measure to solve and input the measurement of each angle.
