Problem J1: Triangle Times

Problem DescriptionCopy Anchor Link

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.
