Question
34. A triangle has side lengths 27,79, and 80. Classify it as an acute, obtuse, or right.
### Triangle Classification

#### Problem Statement:
A triangle has side lengths 27, 79, and 80. Classify it as acute, obtuse, or right.

#### Answer Choices:
A. Not enough info to tell  
B. Obtuse  
C. Right  
D. Acute

#### Instructions to Students:
To classify the given triangle, consider applying the properties of triangles and the Pythagorean theorem. Determine if the triangle is:
- **Acute**: All angles are less than 90 degrees.
- **Right**: One angle is exactly 90 degrees.
- **Obtuse**: One angle is greater than 90 degrees.

Evaluate by considering the lengths of the sides to see which type of triangle they form. 

This problem helps in understanding the fundamental concepts of triangle classification based on side lengths and angle measures.
