```Question 423008
Use a corollary of the converse of the pythagorean theorem, found <a href="http://en.wikipedia.org/wiki/Pythagorean_theorem#Converse">here</a>.

This is what the corollary states:

A corollary of the Pythagorean theorem's converse is a simple means of determining whether a triangle is right, obtuse, or acute, as follows. Where c is chosen to be the longest of the three sides and a + b > c&#8194;(otherwise there is no triangle according to the triangle inequality). The following statements apply:[28]

* If a^2 + b^2 = c^2, then the triangle is right.
* If a^2 + b^2 > c^2, then the triangle is acute.
* If a^2 + b^2 < c^2, then the triangle is obtuse
