Ruler and compass construction of a heart

My take on the parametric heart shape concept.
A: 90 B: 90 There are many ways to use math to define a heart curve. The second one on that page, a sextic algebraic equation, $$(x^2+y^2-1)^3 + x^2y^3 = 0$$, strikes me as one of the most elegant, but it’s not very… adjustable.
Rather than using a single polar/parametric/algebraic equation to define a curve, I imagined a different approach: a heart shape composed only of two circular arcs and two straight line segments.…
