1.3 - Segment and Angle Addition Practice

Front

What is Segment Addition Postulate?

Back

If B is between A and C, then AB + BC = AC.

Front

Define Angle Addition Postulate.

Back

If point B is in the interior of angle AOC, then m∠AOB + m∠BOC = m∠AOC.

Front

If m∠ABC = 90°, what type of angle is it?

Back

It is a right angle.

Front

What is the sum of the angles in a triangle?

Back

180°.

Front

If two angles are complementary, what is their sum?

Back

90°.

Front

If two angles are supplementary, what is their sum?

Back

180°.

Front

What is the measure of an angle that is 15° less than its complement?

Back

If x is the measure of the angle, then x + (90° - x) = 15°, so x = 37.5°.

Front

Find the length of segment ST if S is at 5 and T is at 17.

Back

ST = 17 - 5 = 12.

Front

If m∠QST = 135°, what is the measure of its supplement?

Back

The supplement is 180° - 135° = 45°.

Front

If B is between A and C and AB = 2 and BC = 11, what is AC?

Back

AC = AB + BC = 2 + 11 = 13.
