Basics of an Involute. How to construct an Involute of Equilateral Triangle???

This video provides a technical walkthrough for constructing an involute specifically derived from an equilateral triangle. An involute is defined as a spiral-like curve created by maintaining tension on a wire as it is unwrapped from the perimeter of a geometric shape. The guide details a step-by-step method using a compass and straightedge to extend lines from each corner and draw connecting circular arcs.
