Confused, . can you use a right triangle to represent the distance the distance between any two points on the coordinate plane? explain.

Yes, after applying the Pythagorean Theorem, use (a squared + b squared = c squared), where as; a and b, are any two angles and c is the hypotenuse or the longest side of the right triangle. In other words yes you can use a right triangle to find the distance between any to points on a coordinate plane using... the Pythagorean Theorem.  

Then just do it (lol)
