Question Analysis

This question is centered around using Pythagorean inequality theorems to classify a triangle. The main task is to determine if the triangle is acute, right, or obtuse by comparing the sum of the squares of the two shorter sides with the square of the longest side.

 

Key Concept Explanation

Pythagorean Theorem: For a right triangle with legs and and hypotenuse , .

Pythagorean Inequality Theorems:

If > (where is the longest side), the triangle is acute.

If < (where is the longest side), the triangle is obtuse.
