Question

You are asking to develop a “Triangle Guessing” game in Python for the assignment. The program accepts the lengths of three (3) sides of a triangle as input from a player. The program output should indicate whether the triangle is a right triangle, an acute triangle, or an obtuse triangle.

1.Tips to help you for this assignment: Make sure each side of the triangle is a positive integer. Use try/except for none positive integer input.

2. Validating the triangle. That is the sum of the lengths of any two sides of a triangle is greater than the length of the third side. Use try/except for invalid sides input.

3. For any wrong input, tell the player what is wrong and asking to re-enter.

4. Allow a player to play multiple times, for example, using a while loop. Remind the player what input to stop the game.

5. Develop your game/program a user friendly one. Document your program by adding comments: Introduce/describe the program including the author, date, goal/purpose of the program Document every variable used at the program even the name is meaningful Explain/comment operation/activity/logic of your code. For example, “Checking whether the inputs are positive integers” and “Checking the validity the 3 lengths to see if they are able to form a triangle”

6. Testing your program for all possible input and every of the 3 possible triangles

Program

'''
   Program to find the type of triangle
   Accept only positive integers as sides of triangle
   Check valid triangle, two sides always greater than 3rd side
   Find largest side from 3 sides
   Use pythogorean concept to find type of triangle
'''
#Function treturn largest side from given 3 sides

Output

Enter side1 length: -5
Oops! That was not a positive integer number. Try again...
Enter side1 length: 1
Enter side2 length: 10
Enter side3 length: 12
Error!!Sum of 2 sides of a triangle must be greater than third side!!
Enter side1 length: 7
Enter side2 length: 10
Enter side3 length: 5
Given triangle is obtuse triangle!!!
Do you want to check other triangle(y/n): t
ERROR!!Please enter y or n
Do you want to check other triangle(y/n): y
Enter side1 length: 8
Enter side2 length: 17
Enter side3 length: 15
Given triangle is right angle triangle!!!
Do you want to check other triangle(y/n): y
Enter side1 length: 4
Enter side2 length: 6
Enter side3 length: 7
Given triangle is acute triangle!!!
Do you want to check other triangle(y/n): n
