Most of us do not certainly think about geometry while relaxing at the beach, but a basic bikini is a composition of triangles (bra) and inverted isosceles trapezoids (bottoms). But it is not rare to spot other types of summer geometries in vintage bathing suits like this one from the Met Museum archive.
Designed by Emilio Pucci in 1969 ca. for Saks Fifth Avenue, it is not your average one-piece bathing suit as it is made with two kite-shaped panels on the front. A kite, as some of you may remember from your school days, is a quadrilater in which each pair of consecutive sides are congruent, but opposite sides are not congruent.
If you don't like geometry even when they relate to bathing suits and you'd just wish you were lying on a beach lulled by the waves (whch can be studied also from the point of view of different disciplines, including physics and mathematics…), here's the sound of the waves crashing that I recorded a few days ago as part of another project. Have a lovely Sunday!
