This video explains what the midpoint is, how to solve for x in midpoint problems, and the most important way that midpoint will be used in geometry proofs.
Back to no proofs on this one! We'll just learn this simple formula, and use it on a couple of basic problems before embarking on an awesome word problem example where we'll find the midpoint between L.A. and New York, and even find the name of the Kansas town nearest to it!
If you do not have an account, you should get one, because it is awesome! You can save a playlist for each test or each chapter, and save your "greatest hits" into a "watch right before the final" list (not that we recommend cramming, but when in Rome...)
