Understanding Lines in Geometry

What does it mean when two lines are perpendicular?

• They cross each other at any angle.

• They run alongside each other.

• They never touch or intersect.

• They intersect at a 90 degrees angle.

If one angle formed by two intersecting lines is 90 degrees, what about the other angles?

• They are more than 90 degrees.

• Each of them is also 90 degrees.

• They are less than 90 degrees.

• They can be any angle.

What happens if two lines intersect but not at a right angle?

• They are considered parallel.

• They are neither perpendicular nor parallel.

• They are still perpendicular.

• They form a square.
