To figure out the interior angles you multiply the number of sides minus 2 by 180 so for a triangle there are 3 sides so you minus 2 to get 1 multiply it by 180 and you get 180 which is the interior angles of a triangle so to do this one you minus 2 from 6 to get 4 multiply it by 180 and you get 720 degrees
Any triangle where the sum of the angles is over or under 180 cannot exist.
A 45-55-80 triangle can exist, but a 45-55-90 triangle cannot.
A 30-45-105 triangle can exist, but a 80-90-105 triangle cannot.
