This topic focuses on applying the Pythagorean theorem to find the length of a missing side of a triangle, with the solution expressed as a square root value. Students are tasked with solving multiple problems where they need to calculate the missing length based on the given sides of a right-angled triangle. Each problem requires understanding and manipulating radicals as part of the solution process. This set of problems is part of an introductory unit on Pythagoras' theorem.
