What is an example of opposite rays?
Examples of Opposite Rays Ray CD and ray CG are the opposite rays. You can tell because points G, C, and D lie on one straight line. If you picked any other pair of rays, the points that are on those rays do not lie in one straight line.
What is the definition of opposite rays?
Two rays are opposite rays, by definition, if. (1) they have the same endpoint, and. (2) their union is a line. The first letter in the name of a ray always refers to the endpoint of the ray. Therefore, has its endpoint at and has its endpoint at .
What does endpoint mean in geometry?
line segment
Endpoints are the points on either end of a line segment or on one end of a ray. The midpoint of a line segment is the point that lies halfway between the endpoints.
What is the title of the appendix of Descartes book which shows the discovery of the Cartesian plane?
The most famous of Descartes’ treatises, the Discourse on the Method, contains the appendix Geometry that relates for the first time algebraic concepts with geometric objects, giving rise to the emergence of analytic or Cartesian geometry (from Cartesius, the name Descartes in Latin).
Which rays are opposite rays?
Opposite rays are two rays that both start from a common point and go off in exactly opposite directions. Because of this the two rays (QA and QB in the figure above) form a single straight line through the common endpoint Q. When the two rays are opposite, the points A,Q and B are collinear.
What are the two opposite rays?

What do you call someone who works in geometry?
A mathematician who works in the field of geometry is called a geometer . Geometry arose independently in a number of early cultures as a practical way for dealing with lengths, areas, and volumes. Geometry began to see elements of formal mathematical science emerging in Greek mathematics as early as the 6th century BC.
