Answer:
2 acute and 1 right
Step-by-step explanation:
The sum of angles of a triangle is always 180°.
Right angles are 90°, and obtuse angles are more than 90°. If each of the angles in the triangle is more than 0°, there obviously cannot be two angles that measure 90° or more. Just the sum of those two would be 180° or more, and that sum doesn't include the third angle.
So, any triangle can have at most one angle that is 90° or more (right or obtuse). The remaining two angles must be acute for the sum of angles to be 180°.
2 acute and 1 right angle can form a triangle
