Geometry
Geometry is where mathematics becomes visible. Instead of working only with numbers and symbols, you’ll work with shapes, angles, and spaces—the same things you navigate every single day. From proving why certain facts must be true to calculating areas and volumes, geometry teaches you to see the world with mathematical precision. This course builds your ability to reason logically, visualize in two and three dimensions, and apply mathematical thinking to the physical world around you.
