This math topic focuses on applying the Pythagorean theorem to solve for missing sides of right triangles. Each question involves identifying the correct equation to calculate the length of a missing side based on given side lengths of a triangle. The skills practiced include the ability to rearrange and solve the Pythagorean theorem formula: \( a^2 + b^2 = c^2 \), and differentiate when to add or subtract the squares of the given sides to find the square of the unknown side.
