Basic geometry

Front

What are perpendicular lines?

Back

Lines that intersect to form right angles (90 degrees).

Front

What are parallel lines?

Back

Lines that run in the same direction and never meet, no matter how far they are extended.

Front

What is a vertex?

Back

The point where two lines meet or intersect.

Front

What are intersecting lines?

Back

Lines that cross each other at any angle.

Front

What do you call lines that form four right angles when they intersect?

Back

Perpendicular lines.

Front

If line KL is parallel to line MN, what can we say about their relationship?

Back

They will never meet and are always the same distance apart.

Front

How can you identify parallel lines in a figure?

Back

Look for lines that are equidistant and do not intersect.

Front

What is the difference between parallel and perpendicular lines?

Back

Parallel lines never meet, while perpendicular lines intersect at right angles.

Front

Can two lines be both parallel and perpendicular?

Back

No, two lines cannot be both parallel and perpendicular at the same time.

Front

What is an example of perpendicular lines in real life?

Back

The corners of a square or rectangle.
