In geometry, formal interpretations are developed utilizing other identified words or terms. Tright here are, however, three words in geomeattempt that are not formally defined. These words are allude, line and plane, and also are described as the "3 uncharacterized terms of geometry".

While these words are "undefined" in the formal sense, we deserve to still "describe" these words. The descriptions, declared listed below, refer to these words in relation to geomeattempt.

POINT • a suggest shows a location (or position) in room. • a allude has actually no measurement (actual size). • a suggest has actually no size, no width, and no height (thickness). • a allude is generally called with a funding letter. • in the coordinate plane, a suggest is named by an ordered pair, (x,y). While we reexisting a point via a dot, the dot can be very tiny or extremely big. Remember, a allude has actually no size.
The dimension of the dot drawn to recurrent a allude renders no distinction. Points have no size. They ssuggest reexisting a place.
LINE (right line) • a line has no thickness. • a line"s length extends in one measurement. • a line goes on forever in both directions. • a line has actually infinite length, zero width, and also zero elevation. • a line is assumed to be right. • a line is attracted with arrowheads on both ends. • a line is named by a solitary lowersituation script letter, or by any 2 (or more) points which lie on the line.
Lines deserve to be labeled via a single script letter, or by two points on the line,
. The thickness of a line makes no difference.

PLANE • a plane has two dimensions. • a plane forms a level surface extfinishing indefinitely in all directions. • a airplane has actually limitless size, infinite width and zero height (thickness). • a aircraft is drawn as a four-sided number resembling a tablepeak or a parallelogram. • a plane is called by a single letter (plane m) or by 3 coplanar, however non-collinear,* points (plane ABC).
Plane m or Plane ABC. While the diagram of a plane has edges, you must remember that the plane actually has no limits.
* Coldirect points are points that lie on the exact same straight line. Coplanar points are points that line in the exact same aircraft.
