Question

A triangle has sides that measure 2 inches, 7 inches, and 1 inch. Will it be acute, obtuse, or right?

I gotta show how I got my answer

Thanks guys!

Answer 1

I need help please

Answer 2

If it's a right triangle, 7^2 = 2^2 + 1^2
that is clearly false.
Since 7^2 > 2^2 + 1^2 the triangle is obtuse.

Answer 3

the triangle doesn't exist

the two shorter sides aren't enough to "close up" the triangle
