Exploring the Four Types of Angles

What do two rays meeting at a common endpoint form?

• A line

• A vertex

• An angle

• A circle

How is an angle named?

• By the degree of the angle

• Using the endpoint letters

• By its arc color

• Using three points, with the vertex in the middle

What type of angle measures exactly 90 degrees?

• Acute angle

• Obtuse angle

• Straight angle

• Right angle

Which angle is larger than a right angle but smaller than a straight angle?

• Straight angle

• Acute angle

• Obtuse angle

• Right angle

What type of angle measures less than 90 degrees?

• Straight angle

• Acute angle

• Obtuse angle

• Right angle

What is the sum of degrees in a supplementary angle pair?

• 90 degrees

• 360 degrees

• 180 degrees

• 270 degrees

What is the sum of degrees in a complementary angle pair?

• 180 degrees

• 90 degrees

• 45 degrees

• 360 degrees

If two angles form a straight line, they are considered:

• Supplementary angles

• Acute angles

• Obtuse angles

• Complementary angles

If one angle in a supplementary pair is 70 degrees, what is the measure of the other angle?

• 100 degrees

• 110 degrees

• 180 degrees

• 70 degrees

In a complementary angle pair, if one angle measures 60 degrees, what is the measure of the other angle?

• 120 degrees

• 90 degrees

• 60 degrees

• 30 degrees
