This math topic focuses on applying the Pythagorean Theorem to find the length of the hypotenuse or other sides of a right triangle, expressed as a radical (square root) value. The problems provide diagrams of triangles with sides labeled, where students are tasked with calculating unknown side lengths using the relationship \( a^2 + b^2 = c^2 \). This is foundational for understanding distances on a Cartesian grid, an introductory concept related to distance calculation in coordinate geometry. Each question offers a visual and the precise length expression required, enhancing visual learning and algebraic manipulation skills.
