@gogeometry Sorry there was an error in previous post.

New Geometry Challenge! 📐✨ Square ABCD. Ratio 2:1. Angle 53/2°. Your mission: Prove angle BCE = 45° using pure synthetic logic! 🧠🔥 Full statement & hints here: 🔗 gogeometry.com/school-college… #GoGeometry #Math #Geometry #ProblemSolving #STEM

@gogeometry All I have for now is an algebraic proof.

@steph_bernard69 You are correct. Precision is key. While 53/2° is the classical shorthand used in many geometric traditions, the value is indeed arctan(1/2) ≈ 26.565°. In this problem, the structural relationship (the 1:2 ratio) is what matters most for the synthetic proof. Great observation!

@gogeometry it isn't 53/2 = 26.5. The tangent of the given angle must be 1/2 so it is rather 26.56505..

@gogeometry Proof...

@gogeometry @emreorhangeo Proof is completed

@GoodnotesApp I'm thinking of upgrading to iPadOS 26, but as a heavy user, I want to be sure first. Are there any known bugs or performance issues with Goodnotes on the new OS? Thanks! #Goodnotes #iPadOS26
