Segment and Angle Addition Review

Front

What is the Segment Addition Postulate?

Back

The Segment Addition Postulate states that if point B is between points A and C, then AB + BC = AC.

Front

What is the Angle Addition Postulate?

Back

The Angle Addition Postulate states that if point B is in the interior of angle AOC, then m∠AOB + m∠BOC = m∠AOC.

If m∠RST = (12x - 1)° and m∠RSU = (9x - 15)°, how do you find x if m∠UST = 53°?

Back

Set up the equation: (12x - 1) + (9x - 15) + 53 = 180. Solve for x.
