Perpendicular, Parallel, and Intersecting Lines Exit Ticket

Front

What are perpendicular lines?

Back

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

Front

What are parallel lines?

Back

Parallel lines are lines that run in the same direction and never intersect, no matter how far they are extended.

Front

What are intersecting lines?

Back

Intersecting lines are lines that cross each other at any angle.

Front

Give an example of perpendicular lines.

Back

The edges of a square are perpendicular to each other.

Front

Give an example of parallel lines.

Back

The rails of a train track are parallel lines.

Front

Give an example of intersecting lines.

Back

The hands of a clock intersect at different times.

Front

How can you identify perpendicular lines in a diagram?

Back

Look for a small square symbol at the intersection, indicating a right angle.

Front

How can you identify parallel lines in a diagram?

Back

Parallel lines will have arrows on them pointing in the same direction.

Front

How can you identify intersecting lines in a diagram?

Back

Intersecting lines will cross each other at any angle without any special symbols.

Front

What is the angle formed by perpendicular lines?

Back

Perpendicular lines form a right angle, which is 90 degrees.
