The video tutorial covers two geometric proofs. The first proof demonstrates the equality of two angles, A and B, both measuring 20 degrees, using the transitive property. The second proof involves a more complex scenario with a figure containing multiple rays and bisectors. The goal is to prove that the sum of two angles equals a larger angle, using given bisectors and angle addition. The tutorial emphasizes the importance of writing out steps and using statements and reasons to arrive at the correct conclusion.
