<!-- More Geometry Snacks #1 (What Fraction is Shaded?), drawn by hand as a ruler-and-compass construction.
     A square ABCD on the hidden points A and B: perpendiculars to AB at A and B, cut by the circles of radius AB about
     them. The handle P is a point inside the square, free in both directions; the triangles on the top and the bottom
     sides with their apex at P are shaded. Their area is half the square's wherever P is, a side included. -->
