3 BASIC TERMS OF GEOMETRY:
Point - a dot on a page. A point has no dimensions (length, width, height), it is usually represent by a capital letter and a dot on a page. Think of it as an infinitely small place or position on a map.
Line - an unlimited number of points along the same path. The set of points may be straight or form a curve. Normally, the term 'line' means a straight line. The 'line' has no dimensions (length, width, height) and extends unlimited in both directions. (The part of a line defined by two points, called 'endpoints', is call a line segment or 'segment'.) A 'line' is represented by a drawn line with arrowheads on each end to represent that it doesn't have endpoints. A line can be named in two ways: (1) use the capital letters representing two points on the line and place a double-headed arrow above the two letters (2) use a lowercase letter beside the line to represent it.
Plane - a flat surface that extends indefinitely in all directions. It is usually represented by a parallelogram (four sided figure) with a capital letter in one corner. Remember the plane is not limited by the parallelogram, it extends infinitely. The plane can also be represented by using three points that lie on the plane surface but not on the same line (noncollinear).
SUBSET OF A LINE:
The line, itself, is a subset (though not a proper subset). A ray is a subset of a line with one end-point which extends in only one direction. A line segment is a subset of a line with two end points. A point is a subset of a line. Finally, nothing is a subset (the null subset) of a line. in geometry , a shape consist of a planes, and any plane consist of a connection of planes, and any break down lines, you can then subsets --- line segments and rays by learning about the line and its subsets.
In geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angle is also used to designate the
