VRML Points, Lines, and Planes
Back Geometry Contents Index Home
The following links hop to VRML worlds that present several fundamental Euclidean geometry concepts regarding points, lines, and planes. You will need a VRML 2.0, also called VRML97, compliant browser to see them. Questions about that? Go to here.
After visiting one of these worlds, use the back button on your browser to return to this page.
While browsing these VRML worlds be sure to spin the diagrams to get viewpoints from several different vantage points.
Multiple names for a line, collinear points
Three noncollinear points determine a plane
A plane can not be determined by two points
A plane can not be determined by collinear points
When two lines intersect, they usually intersect at a point
Two lines that do not intersect
When two planes intersect they intersect at a line
