Question 1

What does it mean for two lines to be perpendicular?

Accepted Answer

Two lines are perpendicular if they intersect at a right angle (90 degrees).

Question 2

How can you tell if two lines are perpendicular using their equations?

Accepted Answer

By checking if the product of their slopes is -1.

Question 3

Can perpendicular lines exist in three-dimensional space?

Accepted Answer

Yes, perpendicular lines can exist in three-dimensional space, forming right angles with each other.

Question 4

What is the perpendicular slope of a line with a slope of 4?

Accepted Answer

The perpendicular slope would be -1/4.

Question 5

How does a perpendicular calculator work?

Accepted Answer

A perpendicular calculator determines if two lines are perpendicular by calculating the slopes and checking if their product is -1.
