You've already got a handle on basic angle relationships like complementary, supplementary, and vertical angles. Now we're going to layer on relationships that happen when lines are parallel, and how angles work inside triangles. These are your heavy-hitters for solving more complex problems.

Finding unknown angles often boils down to recognizing specific angle relationships and using them to set up simple equations.

Triangles are fundamental in geometry, and understanding them starts with how we name them and how their angles behave.
