Canadian Computing Competition: 2014 Stage 1, Junior #1

You have trouble remembering which type of triangle is which. You write a program to help. Your program reads in three angles (in degrees).

  • If all three angles are 60, output Equilateral.
  • If the three angles add up to 180 and exactly two of the angles are the same, output Isosceles.
  • If the three angles add up to 180 and no two angles are the same, output Scalene.
  • If the three angles do not add up to 180, output Error.

Input Specification

The input consists of three integers, each on a separate line. Each integer will be greater than 0 and less than 180.

Output Specification

Exactly one of Equilateral, Isosceles, Scalene or Error will be printed on one line.

Sample Input 1

60
70
50

Output for Sample Input 1

Scalene

Sample Input 2

60
75
55

Output for Sample Input 2

Error

    Answer

    angle1 = int(input())

    angle2 = int(input())

    angle3 = int(input())

    if angle1 <= 0 or angle2 <= 0 or angle3 <= 0:

    print("Error")

    elif angle1 + angle2 + angle3 != 180:

    print("Error")

    else:

    if angle1 == angle2 == angle3:

    print("Equilateral")

elif angle1 == angle2 or angle2 == angle3 or angle1 == angle3:

    print("Isosceles")

else:

    print("Scalene")
