How do you name the label for perpendicular lines?

Answer 1

Perpendicular lines are typically labeled using a small square or right angle symbol at the intersection point to indicate that they intersect at a 90-degree angle. In mathematical notation, if lines are labeled as line ( l ) and line ( m ), you might express their relationship as ( l \perp m ) to denote that line ( l ) is perpendicular to line ( m ). Additionally, you can use different colors or styles (like dashed lines) to distinguish between perpendicular lines in diagrams.
