Distance and Midpoint Formulas Challenge

The video tutorial covers the distance and midpoint formulas in geometry. It begins with an introduction to the distance formula, explaining how to calculate the distance between two points using the formula d = √((x2 - x1)² + (y2 - y1)²). The instructor provides a detailed example, demonstrating the calculation process. The tutorial then transitions to the midpoint formula, explaining how to find the midpoint of a line segment by averaging the x and y coordinates of two points. Another example is provided to illustrate the midpoint calculation. The video emphasizes understanding the formulas and applying them to solve problems.
