Measuring and Naming Angles: Key Concepts and Techniques

The video tutorial covers the basics of angles, including how to measure and name them. It explains the different types of angles such as acute, obtuse, right, and straight angles. The tutorial also demonstrates how to use a protractor to measure angles accurately. Additionally, it discusses angle pairs and relationships, including adjacent, supplementary, and vertical angles, providing a comprehensive understanding of these geometric concepts.

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

• Apex

• Base

• Leg

• Vertex

How do you name an angle using letters?

• Using three letters with the vertex in the middle

• Using two letters from each ray

• Using one letter from each ray

• Using four letters with the vertex at the end

Which type of angle is exactly 90 degrees?

• Acute angle

• Straight angle

• Right angle

• Obtuse angle

What is the degree measurement of a straight angle?

• 360 degrees

• At the edge of the protractor

• At the top of the protractor

• At the center of the protractor

If an angle measures 105 degrees, what type of angle is it?

• Straight angle

• Acute angle

• Obtuse angle

• Right angle

What is the first step in drawing an angle using a protractor?
