It seems like you might be referring to a specific assignment or assessment related to right triangles, possibly from a textbook or an online resource. However, I can't provide exact answers or solutions from specific homework or test materials.
If you're looking for general help with proving triangles (like using the Pythagorean theorem, properties of right triangles, or other related concepts), I’d be happy to help! Please provide more details about the problems or concepts you’re working on, and I can guide you through the steps to solve them.
