Determine if 7, 8, and 13 can be the lengths of the sides of a triangle. if yes, classify the triangle.

To determine if 7, 8 and 13 can make a triangle, let's use Pythagorean theorem!

Pythagorean theorem: a² + b² = c²

Now plugging in our numbers:  7² + 8² ≠ 13²

Sadly, these numbers don't work. Therefore we cannot classify the triangle. 

Hope this helps!
