Question

A triangle has sides with length of 11 feet 12 feet and 13 feet. Is it a right triangle

Answer 1

Answer:

No

Step-by-step explanation:

It will be a right triangle if it follows Pyhthagoras Theorem . Where the sum of squares of two smaller sides is equal to the square of the 3rd side. Let's check ,

→ 11²+ 12² = 13²

→ 121 + 144 = 169

→ 265 ≠ 169

Hence the ∆ is not a right angled triangle
