About "90 Degrees in a Right Angle"
A right angle measures exactly 90 degrees, forming the foundation of Euclidean geometry and architectural design. According to mathematicians at the Clay Mathematics Institute, the concept of right angles dates back to ancient Egyptian surveyors who used them to create perfectly aligned structures. The British Museum houses artifacts showing how ancient civilizations understood and applied 90-degree angles in construction. Modern architecture and engineering rely on right angles for structural integrity and design precision. The 90-degree angle represents one of humanity's most fundamental geometric concepts, influencing everything from urban planning to computer graphics and navigation systems.
