This video tutorial covers solving geometric problems from chapter 11.5 of the A-level Maths textbook. It includes two exam-style questions. The first question involves expressing vector O2N in terms of vectors A and B and proving the ratio AN to NB is 1:2. The second question demonstrates that the diagonals of a parallelogram bisect each other. The tutorial provides detailed solutions and explanations for each problem, emphasizing vector operations and geometric proofs.
