How do you determine if two lines are perpendicular using their slopes?

Back

If the product of the slopes of two lines is -1, then the lines are perpendicular.

What is the significance of intersecting lines in geometry?

Back

Intersecting lines can create angles, which are fundamental in geometry for measuring and constructing shapes.
