naming angles

Front

What is an angle?

Back

An angle is formed by two rays that share a common endpoint, known as the vertex.

Front

What is the vertex of an angle?

Back

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

Front

How do you denote an angle using three points?

Back

An angle can be denoted using three points, with the vertex point in the middle, such as angle ABC.

Front

What are rays in the context of angles?

Back

Rays are straight lines that start at a point (the vertex) and extend infinitely in one direction.

How do you name an angle formed by two rays?

Back

An angle formed by two rays can be named using the vertex and a point from each ray, such as ∠XYZ.

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

What notation is used to represent an angle?

Back

Angles are typically represented using the symbol '∠' followed by the vertex and points on the rays.

Front

What are the sides of an angle?

Back

The sides of an angle are the two rays that form the angle.

Front

How can you identify the sides of an angle given its notation?

Back

In the notation ∠XYZ, the sides are represented by the rays YZ and XY.

Front

What is the significance of the order of points in naming an angle?

Back

The order of points indicates the vertex and the direction of the rays; the middle point is always the vertex.
