Pythagorean Theorem - Length of Side - Labelled Sides (Equation) (Level 2)

This math topic focuses on applying the Pythagorean theorem to find the length of a missing side in right triangles. Problems require identifying the correct equation representation using the theorem \(a^2 + b^2 = c^2\), where \(a\) and \(b\) are the legs of the triangle and \(c\) is the hypotenuse. Each problem provides multiple answer choices involving mathematical expressions like sums and differences of squares, challenging students to perform accurate calculations and comprehend algebraic representations.
