2 acute and 1 right
Step-by-step explanation:
The sum of angles of a triangle is always .
Right angles are , and obtuse angles are more than . If each of the angles in the triangle is more than 0°, there obviously cannot be two angles that measure or more. Just the sum of those two would be or more, and that sum doesn't include the third angle.
So, any triangle can have at most one angle that is or more (right or obtuse). The remaining two angles must be acute for the sum of angles to be .
2 acute and 1 right angle can form a triangle
