This topic practices solving for missing sides in right triangles using the Pythagorean theorem. Each problem presents a triangle diagram and prompts the learner to identify the correct method: either adding the squares of the other two sides when solving for the hypotenuse, or subtracting the square of one leg from the hypotenuse's square when solving for a leg. The questions are structured to test understanding of the theorem's application, discerning which method is appropriate based on the given scenario and triangle side labels. This is a foundational exercise in applying the Pythagorean theorem correctly.
