Complementary Angles

Adjust angle B using the slider. What happens as angle B changes? [br][br]When angle B is an acute angle, what kind of angle is angle E?[br][br]When angle B is a right angle, what kind of angle is angle E?

Parrallel lines cut by a Transversal

What do you notice about the angles around point A when compared to those around Point B?
Move point C does the relationship stay the same?
What happens when you move the angle matching slider?

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?[br]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?
