Front

What is Segment Addition Postulate?

Back

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

Front

Define Angle Addition Postulate.

Back

If point D is in the interior of angle ABC, then m∠ABD + m∠DBC = m∠ABC.

Front

What are Vertical Angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What are Supplementary Angles?

Back

Two angles that add up to 180 degrees.

Front

What are Adjacent Angles?

Back

Two angles that share a common side and a common vertex but do not overlap.

Front

What is a Linear Pair of Angles?

Back

A pair of adjacent angles formed when two lines intersect, which are supplementary.

Front

If ∠A + ∠B = 90 degrees, what type of angles are ∠A and ∠B?

Back

Complementary Angles.

Front

Find the value of ∠A if ∠A + 39° = 90°. What is ∠A?

Back

51 degrees.

Front

If MK = 6 and KL = 8, what is the value of ML?

Back

ML = MK + KL = 6 + 8 = 14.

Front

What is the measure of angle 1 if angle 1 and angle 2 are vertical angles and angle 2 measures 49°?

Back

Angle 1 also measures 49°.
