This math topic involves practicing the Pythagorean theorem, specifically calculating the squared length of the hypotenuse (denoted as 'c') in right-angled triangles. Each problem provides the squared lengths of the other two sides, and students are required to sum these values to find \( c^2 \). Multiple-choice answers are given for each problem, where the student must select the correct value of \( c^2 \). This set of problems is part of a foundational unit on Pythagorean principles aimed at developing students' basic understanding of this theorem.
