Basic Geometric Figures

Front

What is a line segment?

Back

A line segment is a part of a line that has two endpoints.

Front

What are intersecting lines?

Back

Intersecting lines are lines that cross each other at one point.

Front

What is a ray?

Back

A ray is a part of a line that has one endpoint and extends infinitely in one direction.

Front

What are collinear points?

Back

Collinear points are points that lie on the same straight line.

Front

What does it mean for lines to be parallel?

Back

Parallel lines are lines in a plane that never meet; they are always the same distance apart.

Front

How many endpoints does a line have?

Back

A line has no endpoints; it extends infinitely in both directions.

Front

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

Back

A line extends infinitely in both directions, while a line segment has two endpoints.

Front

Can two lines be both intersecting and parallel?

Back

No, two lines cannot be both intersecting and parallel; they are mutually exclusive.

Front

What is the definition of perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

Give an example of collinear points.

Back

Points H, N, K, and I are collinear if they lie on the same line.
