Identify Equation - Labelled (Level 1)

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.
