Triangle Types

Read 3 double numbers (A, B and C) representing the sides of a triangle and arrange them in decreasing order, so that the side A is the biggest of the three sides. Next, determine the type of triangle that they can make, based on the following cases always writing an appropriate message:

• if A ≥ B + C, write the message: NAO FORMA TRIANGULO
• if A² = B² + C², write the message: TRIANGULO RETANGULO
• if A² > B² + C², write the message: TRIANGULO OBTUSANGULO
• if A² < B² + C², write the message: TRIANGULO ACUTANGULO
• if the three sides are the same size, write the message: TRIANGULO EQUILATERO
• if only two sides are the same and the third one is different, write the message: TRIANGULO ISOSCELES
