Perpendicular Lines Geometry Illustration | Math Concepts Visualized #3858324 (License: Personal Use)

This diagram depicts two perpendicular lines: a horizontal line segment labeled ab passing through point m, and a vertical line l intersecting it at m. A small square at the intersection confirms the right angle (θ = 90°), and the notation “< θ = 90°” reinforces this. The figure is part of a set titled “Geometry Illustrations” and serves as a foundational visual for Euclidean geometry concepts.

Used in educational web pages, math tutorials, or interactive geometry lessons to explain perpendicularity, right angles, and coordinate geometry basics. Matches user intent for visual learning, homework help, or curriculum-aligned content.
