Establish by mathematical induction that a set containing n elements has 2^n subsets. Prove that the sum of the interior angles of a polygon having n sides is (n-2) * 180 degrees.

Step 1
A polygon with 1 side does not exist, so there are no interior angles. Therefore, the sum of the degrees of the interior angles is 0, which is equal to 180(1-2) = 180(0) = 0. Thus, the statement holds for n = 1. Show more…
