Question

1.1

Write a python in Jupiter notebook function called trng that takes three numbers x, y, and z, and specifies if those can form a triangle (i.e., returns the word triangle if they can, and Not a triangle otherwise).
Note: In order for three numbers to form a triangle sum of any two of them must be greater than the third one (e.g., x=1, y=2, z=4 cannot form a triangle because x+y is not greater than z even though x+z>y and y+z>x).

2.2 Write a program that gets three numbers from user and by calling the trng function you defined above specify if those numbers could be three sides of a triangle.

Example:
Enter the first number: 3.2
Enter the second number: 4
Enter the third number: 7.5
Not a triangle

Answer 1

Python code:

#1.1)
#trng function
def trng(x,y,z):
    #checking if the sum of any 2 side is greater than the 3rd side
    if(x+y>z and y+z>x and x+z>y):
        #trianle is returned
        return("triangle")
    else:
        #Not a trianle is returned
        return("Not a triangle")
#2.2)
#accepting x
x=float(input("Enter the first number: "))
#accepting y
y=float(input("Enter the second number: "))
#accepting z
z=float(input("Enter the third number: "))
#printing returned of trng function for x,y,z as input
print(trng(x,y,z))
