https://www.cemc.uwaterloo.ca/contests/computing/2014/stage%201/juniorEn.pdf

A simple logic problem that uses if, else-if and else statements

angle1 = int(input())
angle2 = int(input())
angle3 = int(input())
sum_angles = angle1 + angle2 + angle3

if angle1 == angle2 and angle2 == angle3 and sum_angles == 180:
    print("Equilateral")
elif (angle1 == angle2 or angle2 == angle3 or angle1 == angle3)\
 and sum_angles == 180:
    print("Isosceles")
elif angle1 != angle2 and angle2 != angle3 and angle1 != angle3\
 and sum_angles == 180:
    print("Scalene")
else:
    print("Error")
