Complementary Angles
Adjust angle B using the slider. What happens as angle B changes?
When angle B is an acute angle, what kind of angle is angle E?
When angle B is a right angle, what kind of angle is angle E?
Complementary Angles
Parrallel lines cut by a Transversal
What do you notice about the angles around point A when compared to those around Point B?

Exterior Angles of Polygons
Use this construction to investigate the sum of the exterior angles of a polygons.
1. Use the slider to resize the quadrilateral. What is the sum of the exterior angles of a quadrilateral?
2. Use the red point on the quadrilateral to change the angle measures. Now use the slider to resize the quadrilateral. Does changing the angle measures effect the sum of the exterior anlges?
