just because I wanted to...

Spoiler:
Given: A sphere with triangle ABC, m(angleA)+m(angleB)=90 degrees
Proof: A perpendicular angle is not 90 degrees

Using the Lobachevskian Postulate, the sum of the angles of a triangle is less than 180 degrees. Because m(angleA)+m(angleB)=90 degrees, then angle C is a perpendicular angle on the sphere. Since 90+m(angleC)<180, m(angleC)<90. Therefore, a perpendiculare angle is not 90 degrees.


boredom really has no limits...
