•Point- In math, a point is an exact location on a plane. A plane is a 2-dimensional, flat surface. A point is usually marked by a dot and a capital letter. Points can be used to name angles and shapes, such as rectangle ABCD or line segment YZ.
•Line-It is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is sometimes called a straight line or, more archaically, a right line (Casey 1893), to emphasize that it has no "wiggles" anywhere along its length.
•Line segment-A line segment has two endpoints. It contains these endpoints and all the points of the line between them. You can measure the length of a segment, but not of a line. ...
•Ray- A ray is a part of a line that has one endpoint and goes on infinitely in only one direction
•Angles-an angle can be defined as the figure formed by two rays meeting at a common end point. An angle is represented by the symbol ∠. ... Angles are measured in degrees, using a protractor.
