Find the perimeter of a triangle on a coordinate plane | Geometry

The video tutorial explains how to find the perimeter of a triangle using both the Pythagorean theorem and the distance formula. It begins by defining the perimeter as the sum of all side lengths and demonstrates how to identify points on a coordinate grid. The tutorial then explores two methods for calculating distances: creating right triangles and using the distance formula. It provides step-by-step calculations for each side of the triangle and concludes by summing these distances to find the perimeter.
