Geometry Basics

Define a line.

• A part of a line that has two endpoints

• A straight path of points that goes on and on in two directions

• A part of a line that has one endpoint and extends infinitely in one direction

• An exact location in space

What is a line segment?

• A part of a line that has two endpoints

• A straight path of points that goes on and on in two directions

• A part of a line that has one endpoint and extends infinitely in one direction

• An exact location in space

Identify the figure: A part of a line that has one endpoint and extends infinitely in one direction.

• Line

• Line Segment

• Ray

• Point

Which of the following statements is true about congruent segments?

• They have the same length.

• They are parallel.

• They intersect at a right angle.

• They are part of the same line.

Which of the following points are collinear?

• Points that lie on the same line

• Points that lie on different lines

• Points that form a triangle

• Points that lie on the same plane but not on the same line

Analyze the arrangement: Points A, B, and C do not lie on the same line. What are these points called?

• Collinear points

• Non-collinear points

• Congruent points

• Parallel points

Describe a plane.

• A part of a line that has two endpoints

• A straight path of points that goes on and on in two directions

• A flat surface that extends infinitely in all directions

• An exact location in space
