Question

A triangle has sides with lengths of 4 meters, 5 meters, and 8 meters. It is a right triangle ?

Answer 1

No

Explanation:

Using the converse of Pythagoras' identity

If the square on the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.

longest side = 8 , and 8² = 64

4² + 5² = 16 + 25 = 41

Since 41 ≠ 64

Then triangle is not right

Answer 2

the triangle is not right angle triangle
