Kinematic method
in dynamical geometry |

The interactive figures on these web pages correspond to the figures in
the paper "The kinematic method and the Geometer's Sketchpad in geometrical
problems", written by
Dr. Alfinio Flores, to be published by the
International Journal of Computers for Mathematical Learning.
Abstract
Segments of dynamical geometrical figures are considered as changing
vectors. Using relationships between the velocities of the endpoints of
those vectors, relations between the vectors are established using the
kinematic method.

Instructions
- Click and drag on red points to move them.
- Click on buttons (when displayed) inside the sketch to cause objects to move,
or new objects to appear and disappear. (If a button stays down
when you click it, you can click a second time to release it.)
- When objects are animating or moving, press '>' to speed up
motion or '<' to slow it down.
- Press 'r' on your keyboard to reset the sketch to its initial configuration.
- If the screen becomes cluttered with traced objects, click the
red 'X'
(when displayed) in the lower-right corner to clear the traces.
