Activity 1: Naming Angles

Front

What is an angle?

Back

An angle is formed by two rays (sides) that share a common endpoint (vertex).

Front

What is the vertex of an angle?

Back

The vertex is the point where the two rays of an angle meet.

Front

What are the different ways to name an angle?

Back

An angle can be named using its vertex and a point on each ray, or by using a number associated with the angle.

Front

What does it mean for angles to be congruent?

Back

Congruent angles are angles that have the same measure.

Front

How do you identify the wrong representation of an angle?

Back

The wrong representation of an angle can be identified by checking if the angle's vertex is correctly labeled and if the rays are in the correct order.

Front

What is the correct way to name angle ∠ABC?

Back

Angle ∠ABC can also be named as ∠CBA or simply as ∠B, as long as the vertex is in the middle.

Front

What is the importance of the order of points when naming an angle?

Back

The order of points is important because it indicates the direction of the angle being measured.

Front

What is a ray in geometry?

Back

A ray is a part of a line that starts at a point and extends infinitely in one direction.

Front

What is the difference between an angle and a line segment?

Back

An angle is formed by two rays, while a line segment is a part of a line that has two endpoints.

Front

How can you tell if two angles are the same?

Back

Two angles are the same if they can be measured to have the same degree or radian measure.
