Question

Explain why all triangles have at least two acute angles.

If two angle measures of a triangle were each greater than or equal to
(90, 180) the sum of the three angle measures would be (greater than 90, greater than 180)
which is not possible.

Answer 1

Answer: all 3 angle measures have to equal 180 degrees. So if two of them are more than 90 degrees, the sum of the angles would be greater than 180.
