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.

Symbol for a line

Multiple names for a line, collinear points

Noncollinear points

Lines not explicitly drawn

Lines plainly drawn

---

Symbol for a ray

A few rays

Symbol for a plane

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
