Question Analysis
The main focus is to apply the Pythagorean Theorem Converse to check if the given triangle is a right - triangle. We must compare the sum of the squares of the two shorter sides with the square of the longest side.
Key Concept Explanation
The Pythagorean Theorem Converse states that for a triangle with side lengths , , and (where is the longest side), if , then the triangle is a right - triangle.
Step - by - Step Solution
1. Identify the longest side:
Calculate the squares of the sides: , , .
Comparing the values, the longest side , and the two shorter sides are and .
2. Calculate the sum of the squares of the two shorter sides:
