How to label the sides of an angle

The video tutorial addresses common student issues with naming angles and explains three methods for labeling angles: using three points, the vertex, or a label inside. It also covers the concept of angle sides, differentiating between rays and line segments, and emphasizes the importance of understanding these concepts for accurate angle representation.

Which of the following is a method to label an angle using three points?

• Angle ABC

• Angle X

• Angle 123

• Angle B

What is another way to label an angle besides using three points?

• Using a single point as the vertex

• Using a shape

• Using a color

• Using a number outside the angle

What is the significance of the vertex in an angle?

• It is the midpoint of the angle

• It is the endpoint of the angle

• It is the starting point of the angle

• It is the point where the sides of the angle meet

How are the sides of angle BAC represented?

• Rays AB and AC

• Lines AB and AC

• Points A, B, and C

• Line segments AB and AC

What distinguishes a ray from a line segment in the context of angle sides?

• A ray continues indefinitely in one direction

• A line segment extends infinitely

• A line segment has no endpoints

• A ray has a fixed length
