Question

A triangle has sides of lengths 12, 14, and 19. Is it a right triangle? Explain.

Answer 1

Check using the Pythagorean Theorem...A² + B² = C²

C is the hypotenuses...which would be the biggest number here

so check

so 12² + 14² = 19²?

written differently

does \[\sqrt{12² + 14²} = 19?\]

No, not quite....19² is 361

12² = 144 and 14² is 196...196+144 is 340

340 doesnt equal 361 lol so no it is NOT a right triangle
