Monge &
d'Alembert Three Circles Theorem I with Dynamic Geometry
You can alter the geometric construction dynamically in order to test
and prove (or disproved) conjectures and gain mathematical insight that
is less readily available with static drawings by hand. Requires
Java Plug-in 1.3 or higher. Please be patient while the applet loads
on your computer. If you are using a dial-up connection, it may take a
few minutes but is well worth the wait. Cabri, GSP, Cinderella, C.a.R. |
