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

Geometry is a part of mathematics that deals with the relationships of points, lines, angles, surfaces, solids measurement, and properties. There are two types of geometry: 2D or plane …

Essential stuff for describing the world around you. 1. Lines and angles. 2. Related angles. What about angles bigger than 360 degrees? 3. Triangles. See if it's really true, and then prove it! …

Geometry is the field of mathematics dealing with figures in a given space. It is one of the two oldest branches of mathematics, along with arithmetic (which eventually branched into number …

Geometry is, with arithmetic, one of the oldest branches of mathematics. It is concerned with properties of space that are related with distance, shape, size, and relative position of figures.

The meaning of GEOMETRY is a branch of mathematics that deals with the measurement, properties, and relationships of points, lines, angles, surfaces, and solids; broadly : the study …
