Geometry is the branch of mathematics that deals with the properties and relationships of points, lines, surfaces, and solids. Whether you’re calculating the area of a triangle or understanding the properties of a circle, geometry is everywhere around us. Let’s see how well you understand these fundamental concepts. Good luck, and enjoy the challenge!
