B$.$ Triangle Function

B$1.$ Define a function which will determine a triangle after passing three internal angles between $0-180$ degrees: $-$ if the sum of the three internal angles is equal to $180$ degrees then it is a valid triangle $-$ you also need to check whether this triangle is $($a$)$ acute, $($b$)$ obtuse, or $($c$)$ right $-$ otherwise, it is not a valid triangle $-$ The function will return a message of the triangle type.
