Yes, the time has come. The day when we all celebrate the sacred (not) circle constant, τ. Fun fact: if you Google "Tau Day", it's a real thing! So, τ. The number that is equal to 2π. Why is τ right and π wrong? Think of a circle with radius 1. Now, before I state … Continue reading Happy Tau Day!

# A neat way to calculate the area of a rectangle

I was sitting down, solving one of Catriona Shearer's geometry puzzles when I found this (by myself): Look, I know it's not the best of drawings, but it's what I did. If we call the long diagonal x, and the line segment perpendicular to the diagonal y, then the area of the triangle = xy/2, … Continue reading A neat way to calculate the area of a rectangle

# Pythagoras’s theorem^2+n^2 = proof^2

Did anything stand out? maybe the m^2+n^2 = f^2 bit? That is Pythagoras's theorem. That? This is what it's like: Pythagoras's theorem, in triangles and squares Link: https://upload.wikimedia.org/wikipedia/commons/thumb/d/d2/Pythagorean.svg/260px-Pythagorean.svg.png Pythagoras's theorem states that, if the triangle is a right-angled triangle, a^2 + b^2 = c^2. Sure, this is one proof: prove it! Link: https://i.stack.imgur.com/POhH1.png But for … Continue reading Pythagoras’s theorem^2+n^2 = proof^2
