Question

A triangle can have:

1. A. Two right angles
2. B. One obtuse angle and one right angle
3. C. Only one right or one obtuse angle (Correct answer)
4. D. Three acute angles each measuring more than 60°

Correct Answer

Option C — Only one right or one obtuse angle

Detailed Solution & Explanation

The correct answer is Only one right or one obtuse angle.

Key Points

• The angles of a triangle sum to 180°.
• Two right angles would already total 180°, leaving 0° for the third — impossible.
• A right and an obtuse angle exceed 180°.
• Three angles each above 60° would exceed 180°.
• So a triangle can contain at most one angle that is right or obtuse.
• This 'angle-sum = 180°' constraint is the single fact that eliminates all three wrong options.
