Landon welded three pieces of metal together to form a triangle with side lengths that measure 8 inches, 9 inches and 17 inches. Is the triangle that Landon created a right triangle?

Step-by-step explanation:

In order to know whether the triangle is a right angle, we need to show that the square of the longest side is equal to the sum of the square of the other two sides

Longest side = 17in

other two sides = 8in and 9in

Check:

17² = 289

Sum of the square of other two sides

= 8² +9²

= 64 + 81

= 145

Since 17² ≠ 8² +9², hence the triangle that Landon created is not a right triangle
