Law of Sines
This is one way of proving the law of sines.
Some items that are eluded to but not shown that an individual should understand are:
- Division of fractions
- The definition of a midpoint
- The definition of a midpoint
- Inscribed angle theorem
- Central angle Theorem
Disclaimer: Proofs are met with much scrutiny. While this proof could be more concise I have tried to show new students how such a proof may be constructed using GeoGebra with the use of static text mixed with dynamic text, LaTeX, and Objects.
