Pythagorean Theorem - Either Missing Length (Radical) (Level 1)

This math topic covers the Pythagorean Theorem focusing on finding the missing length in simple 2D triangles and extends to a 3D introductory context. The problems require calculating the length of a missing side represented as the square root of a number, providing real-world applications of this theorem. Each question is accompanied by multiple choice answers, presented as different square root values, which strengthens understanding of radical expressions and reinforces practical solving skills in geometry.
