Space

Space - Names that identify a place in space or describe how to move in space.

[|Vertex]- The common endpoint of two or more [|rays] or [|line segments] (mkm)

Plane- A plane is a flat, two-dimensional object. We often represent a plane by a piece of paper, a blackboard, or the top of a desk. In fact, none of these is actually a plane, because a plane must continue infinitely in all directions and have no thickness at all. A plane can be defined by two intersecting lines or by three non-collinear points.

__Coordinate plane__- consists of two axes and four quadrants. The two axes are formed by two perpendicular number lines. The horizontal number line is called the x-axis and the vertical number line is called the y-axis. The center of the coordinate plane (or the intersecting point of the two number lines) is called the origin (0,0). The locations of points on the plane can be plotted when one coordinate from each of the axes are used. They are called ordered pairs (x, y). (JMG)

__[|Line]__: a continuous extent of length, straight or curved, without breadth or thickness; the trace of a moving point. (MLS)

A prism is a space figure with two congruent, parallel bases that are polygons. []
 * Prism (fdy) **

[|Translation] - moving a shape without rotating, resizing or anything else, just moving. (hld)

[|Symmetry]- The quality of being made up of exactly similar parts facing each other or around an axis. When one shape becomes exactly like another if you flip, slide or turn it. (JRP)

**mathematical space** - (mathematics) any set of points that satisfy a set of postulates of some kind; "assume that the topological space is finite dimensional"
For activity and mathematical link:

**Words to describe space**:
open,confined, restricted, expansive. topology, in, on, right, left, beside, behind
 * Words to describe places in space**:
 * Words to describe movement in space:**
 * gallop, freeze, run, jump hop, skip.**

[|Volume] The amount of space used by an object. (rec)

[|Reflection] - to flip a shape or show its ‘mirror image” from various angles without changing its shape or size. (mnj)

[|Rotation] - to turn a shape in any direction about a fixed point (JLH)

Graph of an Equation or Inequality The picture obtained by plotting all the [|points] of an [|equation] or [|inequality]. (JPL) []

Curve - used to indicate any path, whether actually curved or straight, closed or open. A curve can be on a plane or in a three-dimensional space. [] (rj).


 * Infinity -** the idea of something that has no end. http://www.mathsisfun.com/numbers/infinity.html (jpb)
