find angle in triangle with python

i try to find an angle of triangle with rules: If the total of the three numbers = 180, then check again: If the three corners of the triangle form an acute angle with a magnitude between 0 ° to 90 °, then print the words "acute angle" If one of the corners is an obtuse angle whose magnitude is between 90 ° to 180 °, then print the words "obtuse angle" If one of the corners is a right angle whose magnitude is 90 °, then print the words "carpenter's triangle" If the total of the three numbers is not 180, then print the words "NOT TRIANGLE"

this my program but i got wrong output:

A = int(input("enter the number of 1 : "))
B = int(input("enter the number of 2 : "))
C = int(input("enter the number of 3 : "))

if(A+B+C <= 90):
    print("acute angle")
if(  90>A<=180 or 90>B<=180 or 90>C<=180 ):
    print("obtuse angle")
if(A+B+C > 180):
    print("NOT TRIANGLE")
    break
if(A==90 or B==90 or C==90):
    print("carpenter's triangle")

i need your opinion to fix this program

Here is one solution you can try:

# If sum of angles makes upto 180; then a triangle 
if(A+B+C == 180):
  # if atleast one side is 90; then Carpenter's triangle
  if(A==90 or B==90 or C==90):
    print("Carpenter's triangle")
  # if all sides are less than 90; then Accute triangle
  elif(A<90 and B<90 and C<90):
    print("Accute triangle")
  # if atleast one side is greater than 90; then Obtuce triangle
  elif(90>A<=180 or 90>B<=180 or 90>C<=180):
    print("Obtuse triangle")
else:
    print('Not a triangle')

If the three corners of the triangle form an acute angle with a magnitude between 0 ° to 90 °, then print the words "acute angle" If one of the corners is an obtuse angle whose magnitude is between 90 ° to 180 °, then print the words "obtuse angle" If one of the corners is a right angle whose magnitude is 90 °, then print the words "carpenter's triangle" If the total of the three numbers is not 180, then print the words "NOT TRIANGLE"

  • If at least one angle is 90; then it can't be an acute or obtuse triangle

  • If all sides are less than 90; then it can't be an obtuse triangle

  • Hense the the if-else flow

Your if conditions are incorrect. And you should use elif instead of if without first if. Because a triangle can't be acute and obtuse at the same time.

A = int(input("enter the number of 1 : "))
B = int(input("enter the number of 2 : "))
C = int(input("enter the number of 3 : "))

if A+B+C != 180 or A<0 or A>180 or B<0 or B>180 or C<0 or C>180:
    print("NOT TRIANGLE")

elif A<90 and B<90 and C<90:
    print("acute angle")

elif (A>90 and A<180) or (B>90 and B<180) or (C>90 and C<180):
    print("obtuse angle")

elif A==90 or B==90 or C==90:
    print("carpenter's triangle")

else:
    print("Wut?")

Hmmm, If I understand you right:

if A+B+C != 180:
    #Cannot be a triangle
    print("Not triangle, please enter new values")
else:
    #We can proceed as its a viable entry
    if A < 90 and B < 90 and C < 90:
        print("Acute Angle")
    elif A == 90 or B == 90 or C == 90:
        print("Carpenter's triangle")
    elif A > 90 or B > 90 or C > 90:
        print("Obtuse angle")
    else:
        print("Some other scenario we haven't accounted for")

As your logic stands, you are never getting into your print("acute angle") scenario for a valid triangle.
