A triangle with all angles less than 90 degrees is called what?

Explanation:
All three interior angles are less than 90 degrees. That’s the defining feature of an acute triangle. This distinguishes it from right triangles, which have a 90-degree angle, and obtuse triangles, which have an angle greater than 90 degrees. An equilateral triangle also fits under this umbrella because its angles are all 60 degrees, which are less than 90, but the statement specifically describes the general category for triangles with all acute angles, which is acute.
