The angle of rotation is typically measured in degrees or radians. Tutor-style math help Angles of Rotation: what to notice and how to work it […]

How to Find Complementary, Supplementary, Vertical, Adjacent, and Congruent Angles?

How to Find Complementary, Supplementary, Vertical, Adjacent, and Congruent Angles?

TL;DR: Five angle relationships do most of the work in geometry. Complementary angles add up to 90 degrees. Supplementary ones add up to 180. Vertical angles, the pair sitting across from each other where two lines cross, are always equal. Adjacent angles share a vertex and a side without overlapping. And congruent angles? They simply […]
