The video tutorial explains how to find the distance between two points on a coordinate plane using the Pythagorean theorem. It begins by discussing when you can count horizontal and vertical lines and when you need to use the theorem for diagonal lines. The tutorial provides several example problems, demonstrating how to draw right triangles and calculate the hypotenuse. It also covers finding the perimeter of shapes with diagonal sides and applies these concepts to a real-world scenario involving distances between attractions at Disney World.

What can be directly counted when a line is perfectly horizontal or vertical on a coordinate plane?

• The slope of the line

• The length of any diagonal line

• The length of the horizontal or vertical line

• The distance between any two points
