Can You Solve This Geometry Challenge? – Find All the Angles @MathQueenSusanne

Uploaded April 2026 | Updated September 2026, 3 weeks ago

In this math video I (Susanne) explain how to solve a problem from a math competition! We construct isosceles triangles, use the sum of angles in a triangle, and set up a system of equations to find all the angles of the figure. Watch step by step as we break down the relationships between the angles and solve the problem clearly and logically. Perfect for anyone who loves a math challenge! Mathematics explained.
