Definition of Angle Addition Postulate
The Angle Addition Postulate states that if point B lies in the interior of angle AOC, then the measure of angle AOB plus the measure of angle BOC equals the measure of angle AOC. In a mathematical expression, this can be represented as:
m∠AOB + m∠BOC = m∠AOC
Here, m represents the measure of the angles. This postulate is essential in solving various geometric problems where angles are involved.
