Solution
first come up with 2 vectors because you\'re going to need to cross them like find the vector AB and BC then you need to cross them to give you a normal vector AB x BC (thats an actual cross product not multiplying them) thatll give you a normal vector, to get a second normal vector multiply it by a scalar
