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.

Now, by using the angle addition postulate formula, we can write ∠1 + ∠2 + ∠3 = 90°. How do you do addition postulates? Find the value of ∠1.
3) For Each Angle, Find M Rsx, M Xst, And Rst.
Add 4 to both sides of the equation. With the angle addition postulate you can find the measurements of angles that you do not know. Euclid defines a plane angle as the inclination to each other, in a plane, of two lines which meet.
Then, Find The Length Of Ab And The Length Of Bc.
