Exploring Angles: Types, Pairs, and Calculating Measurements

What is the point called where two lines or rays intersect to form an angle?

• Intersection

• Corner

• Edge

• Vertex

How can you name an angle using points?

• Using two points

• Using three points with the vertex in the middle

• Using the vertex only

• Using any random point

What is a right angle?

• An angle less than 90 degrees

• An angle exactly 90 degrees

• An angle more than 90 degrees

• An angle that is 180 degrees

Which type of angle is less than 90 degrees?

• Obtuse angle

• Acute angle

• Straight angle

• Right angle

What is the sum of two complementary angles?

• 360 degrees

• 180 degrees

• 90 degrees

• 45 degrees

If one angle of a complementary pair is 30 degrees, what is the measure of the other angle?

• 120 degrees

• 90 degrees

• 60 degrees

• 30 degrees

What is the sum of two supplementary angles?

• 360 degrees

• 180 degrees

• 45 degrees

• 90 degrees

What are adjacent angles?

• Angles that are opposite each other

• Angles that share a vertex and a side

• Angles that sum up to 180 degrees

• Angles that sum up to 90 degrees

What is true about vertical angles?

• They share a common side

• They sum up to 90 degrees

• They are always right angles

• They are always equal

If one angle in a vertical pair is 135 degrees, what is the measure of the opposite angle?

• 90 degrees

• 180 degrees

• 45 degrees

• 135 degrees
