Rational trigonometry Quiz (#2) | WildTrig: Intro to Rational Trigonometry | N J Wildberger

Our second quiz on rational trigonometry, giving four challenging trigonometric problems that can also be tackled with ordinary trigonometry (probably with greater effort and less success, but you can try and see!)
One problem is on vertex bisectors and medians of a particular 6-7-8 triangle, another on squares built inside a pentagon, another on trisecting a right triangle, and the fourth on a flexible quadrilateral.

These problems should be a fun challenge. Warning: they are not easy!

This video is part of the WildTrig series, which introduces Rational Trigonometry and applies it to many different aspects of geometry.
