Question 287332: what is the smallest number of acute angles in any triangle? Explain.
Answer by Deina(147)   (Show Source):
You can put this solution on YOUR website! Given that the inside angles of a standard 2 dimensional triangle equal 180 degrees, and the smallest non-acute angle is 90 degrees, at least two of those 3 inside angles must be < 90 degrees, thus acute.
OTOH, a triangle over a sphere need have zero acute angles, an example would be the triangle of Tokyo, Los Angeles, London.
A triangle drawn encompassing a corner of a cubeoid shape would have 3 90 degree angles.
Do not use this as the answer on a test without discussing it with your instructor first!
And bob's your uncle!
