Supplementary and Complementary Angles
... RT and QS are lines. Therefore, ∠RVT is a straight angle and has a measure of 180°. If ∠RVQ (∠β) is 115°, then ∠QVT (∠α) must be 180° - 115°, or 65°. Since ∠RVS (∠γ) is a vertical angle to ∠QVT, then it is also 65°. Supplementary Angles - Two angles such as ∠α and ∠β in figure 2, whose measures ad ...

... Is it or Is it Not? Draw a circle on a surface where the entire class can view it. Ask children to name it, and then tell why it is a circle. Draw an ellipse (oval) on the same surface. Ask children what it looks like and then ask them to tell why it is not a circle. Draw several other circles and s ...
