That's it! We derived the distance formula! Interestingly, a lot of people don't actually memorize this formula. Instead, they set up a right triangle, and use the Pythagorean theorem whenever they want …

What is the distance formula? The formula gives the distance between two points (x 1, y 1) and (x 2, y 2) on the coordinate plane: (x 2 x 1) 2 + (y 2 y 1) 2

Learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√ ( (x_2-x_1)²+ (y_2 …
