This math topic focuses on applying the Pythagorean theorem to find the length of the hypotenuse of a right triangle, with the sides' lengths given. It involves squaring the lengths of the two shorter sides, summing these squares, and then finding the square root of this sum to solve for the hypotenuse (c). The equations provided in the problems are represented both in text and visually with LaTeX expressions, and multiple choice answers are given for finding the radical (square root) of the hypotenuse. This practice helps reinforce foundational knowledge of the Pythagorean theorem.
