Reuleaux Triangle - Constant Width Curve Geometry Shape #3840941 (License: Personal Use)

This image displays a Reuleaux triangle-a non-circular curve of constant width-constructed by intersecting three identical circles, each centered at a vertex of an equilateral triangle. Its unique geometry allows it to rotate within a square while maintaining contact with all four sides, making it valuable in mechanical linkages and drill bit design. The shape is often used to illustrate concepts in convex geometry and kinematics.

Used in educational math/geometry resources, engineering textbooks, CAD software illustrations, and industrial design references; matches user intent for learning about constant-width shapes or geometric curiosities.
