The name tells you how many sides. If you are given one external angle, say A, then you know that the number of sides multiplied by A =360 since the sum of the exterior anlges is 360. If you are given the sum of the interior angles, you can find the number of side using the formula that sum of interior angles =(number of sides-2)180 degrees.
