Adjacent Angles

Front

What are adjacent angles?

Back

Adjacent angles are two angles that share a common side and a common vertex, but do not overlap.

Front

What is the sum of the measures of adjacent angles that form a straight line?

Back

The sum of the measures of adjacent angles that form a straight line is 180 degrees.

Front

If one angle measures 75 degrees, what is the measure of its adjacent angle if they form a straight line?

Back

The adjacent angle measures 105 degrees.

Front

What is the measure of ∠BAD if ∠CAD is 30 degrees and they are adjacent?

Back

∠BAD measures 123 degrees.

Front

What is the measure of angle A if ∠CAD is 30 degrees and ∠BAD is 75 degrees?

Back

Angle A measures 75 degrees.

Front

If two angles are complementary, what is the relationship between their measures?

Back

The measures of complementary angles add up to 90 degrees.

Front

If ∠CAD is 30 degrees, what is the measure of the other angle if they are complementary?

Back

The other angle measures 60 degrees.

Front

What is the measure of angle A if it is 45 degrees and adjacent to another angle?

Back

Angle A measures 45 degrees.

Front

If the sum of two adjacent angles is 180 degrees, what can we say about their relationship?

Back

They are supplementary angles.

Front

What is the measure of the missing angle if one angle is 25 degrees and they are adjacent?

Back

The missing angle measures 155 degrees.
