Learn geometry—angles, shapes, transformations, proofs, and more.

Geometry is, along with arithmetic, one of the oldest branches of mathematics. A mathematician who works in the field of geometry is called a geometer.

Geometry, the branch of mathematics concerned with the shape of individual objects, spatial relationships among various objects, and the properties of surrounding space.

Geometry is all about shapes and their properties. If you like playing with objects, or like drawing, then geometry is for you!

Geometry is the branch of mathematics that deals with the study of points, lines, angles, surfaces, and solids. Understanding these fundamental concepts lays the foundation for exploring more …

Geometry is a branch of mathematics that deals with shapes, sizes, angles, and dimensions of objects. Explore 2D and 3D shapes, angles in geometry with examples!

Two types of geometry are plane geometry and solid geometry. Plane geometry deals with two-dimensional shapes and planes (x-axis and y-axis), while solid geometry deals with three …
