Adjacent Angles Lesson

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 ∠BAD = 110°, what is the measure of ∠CAD if they are adjacent angles?

Back

∠CAD = 82°.

Front

How do you spell the kind of angles that we are learning about in this lesson?

Back

Adjacent.

Front

What is the measure of angle A if it is adjacent to an angle measuring 90°?

Back

Angle A = 45°.

Front

What is the measure of ∠BCE if it is adjacent to an angle measuring 60°?

Back

∠BCE = 60°.

Front

Which of these is a pair of adjacent angles? Angles KOL and LOM, Angles LOM and LON, Angles KOM and LOM, Angles KOL and MON?

Back

Angles KOL and LOM.

Front

What is the sum of the measures of two adjacent angles?

Back

The sum of the measures of two adjacent angles can vary, but they can be complementary (sum to 90°) or supplementary (sum to 180°).

Front

If one angle measures 30° and is adjacent to another angle, what could be the measure of the adjacent angle?

Back

The adjacent angle could measure 60° (complementary) or 150° (supplementary).

Front

What is the relationship between adjacent angles and straight angles?

Back

Adjacent angles can form a straight angle (180°) when their measures add up to 180°.

Front

Can adjacent angles be equal?

Back

Yes, adjacent angles can be equal, for example, two angles measuring 45° each are adjacent.
