Question

Q6: (Sides of a Right Triangle) Write a function that reads three nonzero integers and determines whether they are the sides of a right-angled triangle. The function should take three integer arguments and return 1 (true) if the arguments comprise a right-angled triangle, and 0 (false) otherwise. Use this function in a program that inputs a series of sets of integers. Hint: a^2+b^2=C^2

Answer 1

Code win python

def isright(list):
    list.sort() # sorting to find the largest element
    a = list[0]
    b = list[1]
    c = list[2]
    if a < 0 or b < 0 or c < 0:  # checking if any element is less than zero
        return 0
    else:
        if (a * a + b * b) == c * c: # checking a^2 + b^2 = c^2
            return 1
        else:
            return 0


if __name__ == '__main__':
    n = int(input("Enter the number of series of elements:"))
    data = []
    for i in range(n):
        print("Sides for triangle {i}:".format(i=i+1))
        a = int(input())
        b = int(input())
        c = int(input())
        list = [a, b, c]
        data.append(list)      # storing data in list like [[1,2,3],[2,4,5]]
    for sides in data:
        if isright(sides):
            print("{a},{b},{c} is a right angled triangle".format(a=sides[0], b=sides[1], c=sides[2]))
        else:
            print("{a},{b},{c} is not a right angled triangle".format(a=sides[0], b=sides[1], c=sides[2]))

Output:

Explaination:

Initially take the number of series of elements which the user wants to input which is stored in n. For each series we form a list/array of elements which we store in a list so the data variable has something like this:

data = [[1,2,3], [3,4,5], [5,7,9] and so on]

for each array in data i.e for [1, 2, 3] (initial case according to the example)

then in the function isright we first sort the list of elements i.e if we get say list as [10, 6,9] we need to find the largest of three element which will be our c then we checik the equation a^2 + b^2 = c^2 if it is true or not then return 0 or 1 accordingly.
