Hey PF! I'm going through a textbook right now and it just said "obviously, you can't have an equilateral pentagon with 4 right angles in spherical geometry (Lambert quadrilaterals).(adsbygoogle = window.adsbygoogle || []).push({});

However, I am not able to make the connection. can somebody help me understand why this is?
