![]() Technically, a tuple of n numbers can be understood as the Cartesian coordinates of a location in a n-dimensional Euclidean space. The term may also refer colloquially to a subset of space, a three-dimensional region (or 3D domain), a solid figure. More general three-dimensional spaces are called 3-manifolds. Learning the names of three-dimensional objects. Now for 3D shapes, its named after the number of faces which are called. Two-dimensional shapesThree-dimensional objectsLocation and TransformationAssessmentsPrintable Worksheets. Most commonly, it is the three-dimensional Euclidean space, the Euclidean n-space of dimension n=3 that models physical space. Its basically learning to Count in greek and sticking the suffix gon on the end. A representation of a three-dimensional Cartesian coordinate system with the x-axis pointing towards the observer. ![]() In geometry, a three-dimensional space ( 3D space, 3-space or, rarely, tri-dimensional space) is a mathematical space in which three values ( coordinates) are required to determine the position of a point. Hexa: six, as in hexadecimal, the six-digit codes often used for color in web and graphic design. Dodecahedron: Composed of 12 regular pentagonal faces, three meeting at each vertex. Penta: five, as in the Pentagon in Washington D.C., which is a large building in the shape of a Pentagon. Cylinder: A cylinder is a surface made up of all the points on all the lines that are parallel to one another and pass through a fixed-plane curve. Tetra: four, as in the number of squares in a Tetris block. ( April 2016) ( Learn how and when to remove this template message)Ī representation of a three-dimensional Cartesian coordinate system with the x-axis pointing towards the observer Tri: three, as in triple, meaning three of something. Please help to improve this article by introducing more precise citations. The Earth is like that in some ways, except for one: when you look at it. This article includes a list of general references, but it lacks sufficient corresponding inline citations. All the points on a sphere are at the same distance from its center.
