A triangle has side lengths of 24in., 32in., and 40in. Is the triangle acute, obtuse, or right?

Question

parthkohli · Answer

In general, if $c$ is the largest side and $a,b$ are the other two,$$a^2 + b^2 < c^2 \Rightarrow \rm obtuse$$$$a^2 + b^2 = c^2 \Rightarrow \rm right$$$$a^2 + b^2 > c^2\Rightarrow \rm acute$$

1600 and 1600

parthkohli · Answer

If the (biggest side)^2 is equal to the (sum of the second biggest side)^2 + (sum of the smallest)^2, then it is a right triangle.  This is also called the Pythagorean Theorem.
