Adjacent Angles

Front

What are adjacent angles?

Back

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

Front

If two angles are adjacent and one measures 80°, what is the measure of the other angle if they form a straight line?

Back

The other angle measures 100° because adjacent angles on a straight line sum up to 180°.

Front

What is the sum of two adjacent angles?

Back

The sum of two adjacent angles can vary, but if they form a straight line, their sum is 180°.

Front

If one angle measures 123°, what is the measure of its adjacent angle if they form a straight line?

Back

The adjacent angle measures 57° because 180° - 123° = 57°.

Front

What is the measure of ∠BAD if it is adjacent to an angle measuring 89°?

Back

If ∠BAD and the adjacent angle form a straight line, then ∠BAD measures 91° because 180° - 89° = 91°.

Front

Find the missing angle if one adjacent angle measures 72° and they form a right angle together.

Back

The missing angle measures 18° because 90° - 72° = 18°.

Front

What is the relationship between adjacent angles?

Back

Adjacent angles can be complementary (sum to 90°), supplementary (sum to 180°), or have no specific relationship.

Front

If two adjacent angles are equal, what is the measure of each angle?

Back

Each angle measures 90° because they are complementary.

Front

What is the measure of the missing angle if one adjacent angle is 28° and they form a straight line?

Back

The missing angle measures 152° because 180° - 28° = 152°.

Front

If ∠A measures 92° and is adjacent to ∠B, what is the measure of ∠B if they form a straight line?

Back

∠B measures 88° because 180° - 92° = 88°.
