Types of Angles

What is the relationship between obtuse angles and right angles?

• Obtuse angles are always greater than right angles, which measure 90 degrees.

• Obtuse angles are equal to right angles.

• Obtuse angles are always less than right angles.

• Obtuse angles can be either greater or less than right angles.

What is the sum of angles in a triangle?

• 90 degrees

• 180 degrees

• 360 degrees

• 120 degrees

What are complementary angles?

• Two angles whose measures add up to 90 degrees.

• Two angles that are equal in measure.

• Two angles that add up to 180 degrees.

• Two angles that are adjacent to each other.

What is a reflex angle?

• An angle that measures exactly 180 degrees.

• An angle that measures less than 90 degrees.

• An angle that measures more than 180 degrees but less than 360 degrees.

• An angle that measures exactly 360 degrees.

What are supplementary angles?

• Two angles whose measures add up to 90 degrees.

• Two angles whose measures add up to 180 degrees.

• Two angles that are adjacent to each other.

• Two angles that are equal in measure.

How can you determine if two angles are complementary?

• If the sum of the measures of two angles is 90 degrees, they are complementary.

• If the difference of the measures of two angles is 90 degrees, they are complementary.

• If one angle is twice the measure of the other, they are complementary.

• If the sum of the measures of two angles is 180 degrees, they are complementary.

How can you determine if two angles are supplementary?

• If the sum of the measures of two angles is 180 degrees, they are supplementary.

• If the measures of two angles are equal, they are supplementary.

• If one angle is twice the measure of the other, they are supplementary.

• If the difference between the measures of two angles is 90 degrees, they are supplementary.

How do intersecting lines create angles?

• They create two pairs of opposite angles that are equal and four angles in total.

• They create only one angle at the point of intersection.

• They do not create any angles, only lines.

• They create angles that are all different from each other.

What is a right angle?

• An angle that measures exactly 90 degrees.

• An angle that measures exactly 45 degrees.

• An angle that measures exactly 180 degrees.

• An angle that measures exactly 360 degrees.

What is a straight angle?

• An angle that measures exactly 90 degrees.

• An angle that measures exactly 180 degrees.

• An angle that measures less than 90 degrees.

• An angle that measures more than 180 degrees.
