WT49: Circles in red geometry
A circle in red geometry looks like a rectangular hyperbola with asymptotes parallel to the lines of slope one and minus one. But in the red setting, such a `red' circle still satisfies many of the properties that we are used to for a circle. So this video shares some of the theorems of WildTrig 10, but in a completely different context. This video is part of the WildTrig series, which introduces Rational Trigonometry and applies it to many different aspects of geometry.
