... Polygons are another type of common closed figures. A polygon is C B a closed plane figure bounded by at least three or more line segments. The line segments are called sides, and the point at which the line segments meet is called a vertex. Your child will learn to identify polygons and justify why ...

Ch. 9 GEOMETRY Remember the “Cartesian Coordinate System
... Remember the “Cartesian Coordinate System”? That represented the “xy-plane in space”. A ray is like “half a line”. It starts at one point (called the endpoint) and goes on to infinity in one direction. The other point tells you which direction the line goes. The ray below is the ray DB. ...
