Parallel and Perpendicular lines

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet or intersect, no matter how far they are extended.

Front

What are perpendicular lines?

Back

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

Front

Can parallel lines ever intersect?

Back

No, parallel lines never intersect.

Front

What is an example of parallel lines in real life?

Back

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

Front

What is an example of perpendicular lines in real life?

Back

The corners of a square or rectangle are examples of perpendicular lines.

Front

How can you identify parallel lines in a figure?

Back

Parallel lines can be identified by looking for lines that are equidistant from each other and never meet.

Front

How can you identify perpendicular lines in a figure?

Back

Perpendicular lines can be identified by looking for lines that form a right angle (90 degrees) where they intersect.

Front

What is the relationship between parallel lines and angles?

Back

Parallel lines cut by a transversal create equal corresponding angles.

Front

What is a transversal line?

Back

A transversal line is a line that crosses two or more other lines.

Front

What types of angles are formed when a transversal crosses parallel lines?

Back

When a transversal crosses parallel lines, it forms corresponding angles, alternate interior angles, and alternate exterior angles.
