Segment and Angle Addition

Front

What is the Segment Addition Postulate?

Back

XY + YZ = XZ

Front

If ∠1 and ∠2 form a linear pair, what is the relationship between their measures?

Back

m∠1 + m∠2 = 180°

Front

Calculate m∠1 if m∠1 = (5x + 9)° and m∠2 = (3x + 11)° and they form a linear pair.

Back

m∠1 = 109°

Front

Calculate m∠2 if m∠1 = (5x + 9)° and m∠2 = (3x + 11)° and they form a linear pair.

Back

m∠2 = 71°

Front

What is the formula to find the length of a segment using the Segment Addition Postulate?

Back

If A, B, and C are points on a line, then AB + BC = AC.

Front

If PR = 11 and PQ = 5, what is the length of QR?

Back

QR = PR - PQ = 11 - 5 = 6.

Front

What is the measure of an angle that is complementary to 70°?

Back

The measure is 20°.

Front

What is the measure of an angle that is supplementary to 90°?

Back

The measure is 90°.

Front

If two angles are complementary, what is the sum of their measures?

Back

The sum is 90°.

Front

If two angles are supplementary, what is the sum of their measures?

Back

The sum is 180°.
