Points, Lines, and Planes

Front

What is a point in geometry?

Back

A point is a specific location in space that has no size or dimension.

Front

What is a line in geometry?

Back

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

Front

What is a plane in geometry?

Back

A plane is a flat two-dimensional surface that extends infinitely in all directions.

Front

What are parallel lines?

Back

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

Front

What are perpendicular lines?

Back

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

Front

What are intersecting lines?

Back

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

Front

Can you give an example of parallel lines?

Back

Railroad tracks are an example of parallel lines.

Front

Can you give an example of perpendicular lines?

Back

The edges of a square are examples of perpendicular lines.

Front

What is the relationship between parallel lines and planes?

Back

Parallel lines can exist within the same plane without intersecting.

Front

What is the relationship between perpendicular lines and planes?

Back

Perpendicular lines can intersect within a plane, forming right angles.
