Question 1075104: I need to find two addition postulates. Below are the other given values.
Given:ABC=EBD
Reflection: m∠CBE=m∠CBE
Equal Angles: m∠ABC+m∠CBE=m∠EBD+m∠CBE
Addition Postulate: ?
Addition Postulate: ?
No other information is given except for the picture of the angles with the letters A,B,C,E,D. I do not understand how to find the Addition Postulates. Can someone please help?

You can put this solution on YOUR website! Angle Addition Postulate:
"If point B lies in the interior of angle AOC, then:
m ∠AOB + m ∠ BOC = m ∠ AOC"
Translation
If you place two angles side-by-side, then the measure of the resulting angle will be equal to the sum of the original angles.
:
Segment Addition Postulate:
"If X is on then AX + XB = AB"
Translation:
given 2 points A and C, a third point B lies on the line segment AC if and only if the sum of the distances from AB added to BC = AC. So, AB+BC = AC
