 Circle Chord, Theorems and Problems 1 Euclid's Elements Book I, 23 Definitions. One-page visual illustration. Euclid's Elements Book. Index Common Chord to two circles. Index. Theorems and Problems. Perpendicular Chords. Index. Theorems and Problems. Parallel Chords. Index. Theorems and Problems. Eyeball Theorem: Animated Angle to Geometry Study. Equal chords. Mascheroni construction with compass alone. Index Common chords. Euclid's Elements, Book XIII, Proposition 10 One page visual illustration. Simson Line. A proof of Simson line with animation. Miquel's Pentagram with Dynamic Geometry. You can alter the pentagram 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.
