Complementary/Supplementary/Vertical Angles

What are complementary angles?

• Two angles that add up to 90 degrees.

• Two angles that add up to 180 degrees.

• Two angles that are equal in measure.

• Two angles that are adjacent to each other.

What type of angles are formed when two lines intersect?

• Complementary angles and supplementary angles.

• Vertical angles and adjacent angles.

• Acute angles and obtuse angles.

• Reflex angles and straight angles.

If two angles are supplementary and one measures 102 degrees, what is the measure of the other angle?

• 80 degrees

• 82 degrees

If one angle measures 72 degrees, what is the measure of its complementary angle?

• 18 degrees

• 28 degrees

• 36 degrees

• 45 degrees

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

• 45 degrees

• 90 degrees

• 180 degrees

What are supplementary angles?

• Two angles that add up to 90 degrees.

• Two angles that add up to 180 degrees.

• Two angles that are equal in measure.

• Two angles that are adjacent to each other.

If angle Z is 90 degrees, what can you say about its complementary angle?

• It exists and is 0 degrees.

• It exists and is 45 degrees.

• It does not exist, as complementary angles must add up to 90 degrees.

• It exists and is 90 degrees.

What are vertical angles?

• Angles that are adjacent to each other when two lines intersect; they are always congruent.

• Angles that are opposite each other when two lines intersect; they are always congruent.

• Angles that are supplementary when two lines intersect; they are always equal.

• Angles that are complementary when two lines intersect; they are always different.

What is the measure of an angle that is supplementary to a 70-degree angle?

• 90 degrees

• 110 degrees

• 130 degrees

• 150 degrees

What is the relationship between vertical angles?

• Vertical angles are always equal in measure.

• Vertical angles are complementary.

• Vertical angles are supplementary.

• Vertical angles are never equal.
