Hello, I have 4 types of triangle and I want to classify triangles by their directions: upward, downward, right, left. How can I solve this with image processing?

It's a joke! you can detect triangle and you don't know how to define upward, downward, right, left?

with math, yes. but is there easier way/algorithm built-in? :D
