1. **State the problem:** We are given a triangle with angles 50°, 97°, and 33° and need to determine what kind of triangle it is. 2. **Recall the types of triangles by angles:** - Acute triangle: all angles less than 90° - Right triangle: one angle exactly 90° - Obtuse triangle: one angle greater than 90° 3. **Analyze the given angles:** - 50° is less than 90° - 97° is greater than 90° - 33° is less than 90° 4. Since one angle (97°) is greater than 90°, the triangle is an **obtuse triangle**. **Final answer:** The triangle is an obtuse triangle.
