How is a plane represented in two dimensions?

• As a square

• As a triangle

• As a parallelogram

• As a circle

What is a line segment?

• A part of a line with two endpoints

• A line that extends infinitely

• A plane with no thickness

• A point with no location

How is a ray different from a line segment?

• It forms a closed shape

• It has two endpoints

• It has one endpoint and extends infinitely in one direction

• It has no endpoints

What is formed by two rays, lines, or line segments at their intersection?

• An angle
