Midpoint and Distance Formulas

This video tutorial covers the distance and midpoint formulas. It begins with an introduction to the learning targets, which include calculating the distance and midpoint between two points and determining the appropriate formula to use. The video then explains the distance formula, showing how it relates to the Pythagorean theorem and providing examples of its application. The midpoint formula is also discussed, with examples demonstrating how to calculate the midpoint by averaging the coordinates of two points. Both formulas are presented as tools that do not need to be memorized but can be used effectively with practice.
