# How To Do Angle Addition Postulate

How To Do Angle Addition Postulate. What are the angle properties? ∠abd + ∠dbc = ∠abc we know that ac is a straight line, and straight angles are 180° we also have the formulas for ∠abd and ∠dbc let’s plug ‘em in:

The two angles share the same line bd, so they line up. Then, find the length of ab and the length of bc. I left it pretty blank, by design.
