Parallel, Perpendicular, and Intersecting Lines

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet; they are always the same distance apart.

Front

What does the symbol '∥' represent?

Back

The symbol '∥' represents that two lines are parallel.

Front

What are perpendicular lines?

Back

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

Front

What does the symbol '⊥' represent?

Back

The symbol '⊥' indicates that two lines are perpendicular.

Front

What does it mean for two lines to intersect?

Back

Two lines intersect if they cross each other at one point.

Front

What is the relationship between intersecting lines and angles?

Back

When two lines intersect, they form angles, which can be acute, right, or obtuse.

Front

How can you determine if two lines are parallel using slopes?

Back

Two lines are parallel if they have the same slope.

Front

How can you determine if two lines are perpendicular using slopes?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

What is the significance of the intersection point of two lines?

Back

The intersection point is the location where two lines meet, and it can be used to solve geometric problems.

Front

Can two lines be both parallel and intersecting?

Back

No, two lines cannot be both parallel and intersecting; they are mutually exclusive.
