Front

What is a point?

Back

A point is a fixed position in space that has no dimensions or size.

Front

What is a line?

Back

A line is a straight one-dimensional figure that extends infinitely in both directions.

Front

Back

A line can be named using any two points on the line or a lowercase letter.

Front

How do you name a plane?

Back

A plane can be named using three non-collinear points or a single uppercase letter.

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

What is the relationship between points, lines, and planes?

Back

Points define locations, lines connect points, and planes are formed by lines.

Front

What does it mean for points to be collinear?

Back

Collinear points are points that lie on the same line.
