G.5.B. Angle Relationships

Front

What is the measure of angle JKM if it is given that m< JKM = 38?

Back

m< JKM = 38 degrees.

Front

What does it mean for angles 1 and 2 to be adjacent?

Back

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

Front

Identify the pairs of vertical angles from the following: ∠COB & ∠COA, ∠AOD & ∠AOC, ∠COB & ∠AOD, ∠BOD & ∠AOD.

Back

The pairs of vertical angles are ∠COB & ∠AOD.

Front

If the measure of angle AF is given as 11, what is m< AF?

Back

m< AF = 11 degrees.

Front

What angle relationship is shown when two angles share a common side and vertex?

Back

The angle relationship is called Adjacent.

Front

Define complementary angles.

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

Define supplementary angles.

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What are vertical angles?

Back

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

Front

If angle A measures 45 degrees, what is the measure of its complementary angle?

Back

The complementary angle measures 45 degrees (90 - 45 = 45 degrees).

Front

If angle B measures 120 degrees, what is the measure of its supplementary angle?

Back

The supplementary angle measures 60 degrees (180 - 120 = 60 degrees).
