To find the length of the other leg, we apply the Pythagorean theorem, which states:
a² + b² = c², where c represents the hypotenuse—the longest side in a right triangle—and a and b are the other two legs.
This fundamental principle in geometry remains a cornerstone of spatial reasoning, widely discussed in STEM education, architecture, construction, and digital design. With increasing focus on practical problem-solving and visual literacy, understanding how to calculate unknown sides offers clear value in everyday applications.
