Pythagorean Theorem - Length of Side - Labelled Sides (Decimal) (Level 1)

This math topic focuses on applying the Pythagorean Theorem to calculate the length of missing sides of right triangles in decimal form. The problems require students to identify and solve for missing sides (labeled as a, b, or c) using the formula \( a^2 + b^2 = c^2 \), where \( c \) typically represents the hypotenuse. Each question provides different configurations of right triangles, pushing students to practice and reinforce their skills in handling square roots and squares of decimal numbers within the context of geometry.
