The triangle shown in the image is a **right triangle**, as indicated by the small square marking one of the angles as a right angle (90°).

In any triangle:
- The sum of all angles is always 180°.
- A right triangle has exactly one 90° angle.
- An obtuse angle is one that measures more than 90° but less than 180°.

Since this is a right triangle, it cannot have any obtuse angles because:
- One angle is exactly 90°.
- The other two angles must add up to 90°, making them both less than 90°.

Thus, **this triangle has 0 obtuse angles**.

**Tip:** In a right triangle, the two non-right angles are always acute, meaning less than 90°.
