Parallel, Perpendicular, and Intersecting Lines

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet. They 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 parallel lines ever meet?

Back

No, parallel lines never meet.

Front

What is an example of perpendicular lines?

Back

An example of perpendicular lines is the lines that form the corners of a square.

Front

How can you identify intersecting lines?

Back

You can identify intersecting lines by looking for a point where they cross.

Front

What is the angle formed by perpendicular lines?

Back

The angle formed by perpendicular lines is 90 degrees.

Front

Are all intersecting lines perpendicular?

Back

No, not all intersecting lines are perpendicular; they can intersect at any angle.

Front

What is the distance between parallel lines?

Back

The distance between parallel lines is constant; it does not change.

Front

Can two lines be both parallel and intersecting?

Back

No, two lines cannot be both parallel and intersecting.
