Answer: Choice 2

Only one angle is a right angle and the other two are acute

=================================================

Explanation:

As the name suggests, a right triangle has a right angle. This is a 90 degree angle shown by a small square marker.

This leaves 180-90 = 90 degrees left for the other angles to add to. The other angles must be less than 90 for this to work. Therefore, these other angles are acute.

If we had a right angle and an obtuse angle like 120, then we'd have a sum of 90+120 = 210 which is over the 180 mark. This is why it's impossible to have a right angle and an obtuse angle at the same time for any triangle.
