Step 1: Enter the Equation you want to solve into the editor. used when we do part + part = whole (for either sides or angles). Two intersecting lines form congruent vertical angles OR vertical angles are congruent. When you do that, you are doing a proof. This means they're the most important part of the whole field by a very large measure, but they're generally going to be more difficult than anything else. Given: BD divides ABC into two angles, ABD and DBC Prove: mABD = mABC - mDBC. the justifications of the statements.
