Transversal Line,, Ceva and Menelaus Theorems and Problems - Index
Ceva's theorem shines,
Lines of concurrency meet,
Triangle's essence.
Menelaus weaves his spell,
Ratio's secrets revealed.

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,
