High School Resource
This page focuses on collinear points. Four draggable points are shown which the user can manipulate. Moving one point changes the location of the others so that they remain on the same imaginary line. A button controls whether or not the actual line is shown.
The page can be enlarged to full-screen size for use with a classroom projector. After use in the classroom, students can access it again from any web browser at home or in the library with no login required.
