All angles inscribed in a circle that subtend the same chord are equal
... This theorem is a result of Euclid’s Proposition 111.21: In a circle the angles in the same segment equal one another. It is a simple result with a fairly straightforward proof. It is easy to prove this proposition using Euclid’s Proposition 111.20: In a circle the angle at the center is double the ...
