An architect uses trigonometry in many aspects of their work. They must understand trigonometry to design structures with arches, domes, suspension bridges, and more. Trigonometry allows architects to precisely specify the shapes and forms of a structure so it can be built accurately. It is also used to calculate angles, distances, and material quantities to ensure structural stability and safety. To become an architect requires education including courses in physics, trigonometry, geometry, and engineering, followed by passing licensing exams and apprenticeships.
