Parallel, Intersecting, or Perpendicular Lines?

Front

What are parallel lines?

Back

Parallel lines are lines that never meet or cross each other, no matter how far they are extended. They are always the same distance apart.

Front

What are intersecting lines?

Back

Intersecting lines are lines that cross each other at one point. This point is called the intersection.

Front

What are perpendicular lines?

Back

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

Front

Can parallel lines ever meet?

Back

No, parallel lines never meet or intersect.

Front

Give an example of parallel lines in real life.

Back

The rails of a train track are an example of parallel lines.

Front

Give an example of intersecting lines in real life.

Back

The letter 'X' is formed by intersecting lines.

Front

Give an example of perpendicular lines in real life.

Back

The corners of a square or rectangle are formed by perpendicular lines.

Front

How can you identify parallel lines?

Back

You can identify parallel lines by checking if they are always the same distance apart and never meet.

Front

How can you identify intersecting lines?

Back

You can identify intersecting lines by looking for a point where two lines cross each other.

Front

How can you identify perpendicular lines?

Back

You can identify perpendicular lines by checking if they meet at a right angle (90 degrees).
