Distance Formula Examples

Videos, examples, solutions, and lessons to help Grade 8 students learn how to apply the Pythagorean Theorem to find the distance between two points in a coordinate system.

Common Core: 8.G.8

Suggested Learning Targets

• I can recall the Pythagorean Theorem and its converse and relate it to any two distinct points on a graph.
• I can determine how to create a right triangle from two points on a coordinate graph.
• I can use the Pythagorean Theorem to solve for the distance between the two points. Apply the Pythagorean Theorem to find the distance between two points in a coordinate system 8.G.8

The following figures give the Distance Formula and how the Distance Formula is derived from the Pythagorean Theorem. Scroll down the page for more examples and solutions.
