Function fromRadius

Returns an equilateral triangle centered at the origin.

// Create a triangle at 100,100 with radius of 60
const tri = fromRadius({x:100,y:100}, 60);

// Triangle with point A upwards, B to the right, C to the left
constr tri2 = fromRadius({x:100,y:100}, 60, {initialAngleRadian: -Math.PI / 2});
