AngleVectorGeometric Construction
This applet dynamically demonstrates the concept of supplementary angles to help students understand what it means for angles to be supplementary. Key mathematical concepts include supplementary angles. Construction highlights the use of Rotate, Angle, Ray, Circle, Intersect, Line, Vector commands. Suitable for middle school and above students learning geometry.
