What is an acute triangle?

Explanation:
An acute triangle has all three interior angles less than 90 degrees. The angles in any triangle always sum to 180 degrees, so it’s possible for each angle to be under 90. If any angle were 90 or more, the triangle wouldn’t be acute (it would be right or obtuse). Also, two obtuse angles can’t occur in a Euclidean triangle because their sum would exceed 180. Therefore the description that fits is a triangle with three acute angles.
