Question 1075104
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
