Geometric Compass Constructing an Equilateral Triangle - Educational Diagram #1483350 (License: Personal Use)

This black-and-white line illustration shows a metal drafting compass in action, its legs anchored at points A and B on a baseline, with the pencil tip poised to mark the apex of an equilateral triangle. The compass arms are locked at the distance AB, ensuring all three sides will be equal-a foundational Euclidean construction. Shading on the compass joints adds dimensionality to the technical drawing.

Used in educational contexts-geometry textbooks, online math tutorials, and classroom slides-to demonstrate classical compass-and-straightedge constructions, especially for teaching congruence, symmetry, and proof-based reasoning.
