It's odd that I only recall the SSS, SAS, and ASA congruence rules from elementary school. It was in one of your videos that I had to look up the RHS Congruence Rule, which is what you also use in this video.

As well, I like the way you highlight in color the triangles and line segments of your diagrams in order to make it easier to follow the derivations or proofs in your videos.

I came to this video from your video "Pitot's Theorem Proof. Geometry video." of 25 Jun 2023.

I'm so glad I am subscribed to your channel. Thank you for the short, sweet and interrelated videos you produce.

Aha! Building up to bigger things, I imagine. The seeds of Pitot's Theorem are sown.

About a week ago, I was watching a Short by another maths YouTuber, SQ-MATHQ, who, when demonstrating three formulae for the lengths of common tangents to two circles, had written '2√(R₂ ∙ R₂)' but then said 'two root of R₁ plus R₂'. That little slip-up led me to check which was correct, which led, in turn, to my deriving Euclid's general formula for Pythagorean triples. All right, I was two millennia late with my discovery, but it was still quite satisfying.
