Angle : If two line segments (or rays) both start at a common point the opening between the two line segments is called an angle. The common point is called vertex of the angle. The size of an angle is measured in degrees.
Endpoint : In a line segment AB, A and B are referred to as endpoints of the line segment.
Line : A line AB is a one-dimensional shape that includes the points A and B, all the points on the line segment in between A and B and all the points of the straight extension of the line segment beyond A and B. A line does not have an endpoint.
Line segment : A line segment AB is a one-dimensional shape consisting of the points A and B and all the points on the straight connection of A and B. A and B are both endpoints of the line segment AB.
Number : A number $x$ is a mathematical symbol representing a quantity.
Point : A point is an element in a space. Shapes are made of sets of points.
Ray : A ray AB is a one-dimensional shape that includes the points A and B, all the points of the line segment AB and all the points of the straight extension of the line segment beyond B. The ray AB has exactly one endpoint namely A.
