The vertex of a shape where two edges meet form an angle. Different shapes in geometry have different angle measures. For example: A triangle is a 3 sided shape, and the sum of its 3 interior angles is 180˚. A square, rectangle or quadrilateral are 4 sided shapes, and the sum of their 4 interior angles is 360˚.
Geometry is the branch of mathematics that deals with shapes, angles, dimensions and sizes of a variety of things we see in everyday life. Geometry is derived from Ancient Greek words – ‘Geo’ means ‘Earth’ and ‘metron’ means ‘measurement’. In Euclidean geometry, there are two-dimensional shapes and three-dimensional shapes.

geometry, the branch of mathematics concerned with the shape of individual objects, spatial relationships among various objects, and the properties of surrounding space. It is one of the oldest branches of mathematics, having arisen in response to such practical problems as those found in surveying, and its name is derived from Greek words ...

- On the way to this spurious demonstration, Saccheri established several theorems of non-Euclidean geometry—for example, that according to whether the right, obtuse, or acute hypothesis is true, the sum of the angles of a triangle respectively equals, exceeds, or falls short of 180°. He then destroyed the obtuse hypothesis by an argument that depended upon allowing lines to increase in length indef...
- The pseudosphereThe pseudosphere has constant negative curvature; i.e., it maintains a constant concavity over its entire surface. Unable to be shown in its entirety in an illustration, the pseudosphere tapers to infinity in both directions away from the central disk. The pseudosphere was one of the first models for a non-Euclidean space.
Mathematics. Geometry (from Ancient Greek γεωμετρία (geōmetría) 'land measurement'; from γῆ (gê) 'earth, land' and μέτρον (métron) 'a measure') [1] is a branch of mathematics concerned with properties of space such as the distance, shape, size, and relative position of figures. [2] Geometry is, along with arithmetic, one ...
Geometry is an original field of mathematics, and is indeed the oldest of all sciences, going back at least to the times of Euclid, Pythagoras, and other “natural philosophers” of ancient Greece. Initially, geometry was studied to understand the physical world we live in, and the tradition continues to this day.
Sep 4, 2018 · Simply put, geometry is a branch of mathematics that studies the size, shape, and position of 2-dimensional shapes and 3-dimensional figures. Although ancient Greek mathematician Euclid is typically considered the "Father of Geometry," the study of geometry arose independently in a number of early cultures. Geometry is a word derived from Greek.
