M4 Lesson 3 Exit Ticket Perpendicular Lines 12/12

Front

What are perpendicular lines?

Back

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

Front

Give an example of perpendicular lines in real life.

Back

The edges of a book or the corners of a square are examples of perpendicular lines.

Front

What is the symbol used to represent perpendicular lines?

Back

The symbol for perpendicular lines is ⊥.

Front

How can you identify perpendicular lines in a figure?

Back

Look for two lines that meet at a right angle (90 degrees).

Front

What are parallel lines?

Back

Parallel lines are lines that never intersect and are always the same distance apart.

Front

What is the difference between parallel and perpendicular lines?

Back

Parallel lines never meet, while perpendicular lines intersect at a right angle.

Front

What does it mean if two lines are intersecting?

Back

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

Front

Are all intersecting lines perpendicular?

Back

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

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

Can perpendicular lines be vertical and horizontal?

Back

Yes, a vertical line and a horizontal line are always perpendicular to each other.
