I know this is really basic, but I just can't seem to remember...

Say you have three points (0,0,2),(0,2,0) and (2,0,0) to form a triangle. How do you calculate the normal to the surface?

Hi Natalie89! Welcome to PF!

Hint: it has to be perpendicular to any two vectors in the surface
so find any two vectors, and use the cross product
