Understanding Points, Rays, Lines, and Angles

A ray is part of a ​ (a)   that has one ​ (b)   and continues on ​ (c)   in one direction.

• line
• endpoint
• forever

What is the definition of a point in geometry?

• A two-dimensional shape with no area

• A line with no length

• A circle with a radius of 0

• A location in space with no size or dimension

What is the difference between a ray and a line segment?

• A ray has two endpoints and extends infinitely in both directions, while a line segment has one endpoint and a specific length.

• A ray has one endpoint and extends infinitely in one direction, while a line segment has two endpoints and a specific length.

• A ray and a line segment are the same thing.

• A ray has two endpoints and a specific length, while a line segment extends infinitely in one direction.

Name the figure.

What is the definition of a line in geometry?

• A straight path that extends infinitely in both directions

• A circle with no curves

• A triangle with only two sides

• A square with unequal sides

An angle is formed by two ​ (a)   that share a common ​ (b)   . A ​ (c)   is a straight line of (d)   that extend infinitely in two directions.
