A brief illustrated guide to ‘scissors congruence’ − an ancient geometric idea that’s still fueling cutting‑edge mathematical research

In math class, you probably learned how to compute the area of lots of different shapes by memorizing algebraic formulas. Remember “base x height” for rectangles and “½ base x height” for triangles?
