Write a python program to check if a + b and c are the lengths of three sides of a triangle or not

Python Basic - 1: Exercise-34 with Solution

Write a Python program to check whether three given lengths [integers] of three sides form a right triangle. Print "Yes" if the given sides form a right triangle otherwise print "No".

Input:
Integers separated by a single space.
1 ≤ length of the side ≤ 1,000

Pictorial Presentation:

Sample Solution:

Python Code:

print["Input three integers[sides of a triangle]"]
int_num = list[map[int,input[].split[]]]
x,y,z = sorted[int_num]
if x**2+y**2==z**2:
    print['Yes']
else:
    print['No']

Sample Output:

Input three integers[sides of a triangle]
 8 6 7
No

Table of Contents

This program checks whether given three sides of a triangle forms a valid triangle or not.

In mathematics, the triangle inequality states that for any triangle to be valid, the sum of the lengths of any two sides must be greater than or equal to the length of the remaining side.

If a, b and c are three sides of triangle then following conditions must be satisfied for a valid triangle.

a + b ≤ c

b + c ≤ a

c + a ≤ b

Python Source Code : Validity of Triangle Given Sides

# Validity of Triangle given sides

# Function definition to check validity
def is_valid_triangle[a,b,c]:
    if a+b>=c and b+c>=a and c+a>=b:
        return True
    else:
        return False

# Reading Three Sides
side_a = float[input['Enter length of side a: ']]
side_b = float[input['Enter length of side b: ']]
side_c = float[input['Enter length of side c: ']]

# Function call & making decision

if is_valid_triangle[side_a, side_b, side_c]:
    print['Triangle is Valid.']
else:
    print['Triangle is Invalid.']

Python Output: Validity of Triangle

Run 1:
-----------------
Enter length of side a: 2
Enter length of side b: 2
Enter length of side c: 4
Triangle is Valid.

Run 2:
-----------------
Enter length of side a: 2
Enter length of side b: 4
Enter length of side c: 15
Triangle is Invalid.

Given three sides, check whether triangle is valid or not. 
Examples: 
 

Input :  a = 7, b = 10, c = 5 
Output : Valid

Input : a = 1 b = 10 c = 12 
Output : Invalid

Approach: A triangle is valid if sum of its two sides is greater than the third side. If three sides are a, b and c, then three conditions should be met. 
 

1.a + b > c 
2.a + c > b 
3.b + c > a  

C++

#include

using namespace std;

bool checkValidity[int a, int b, int c]

{

    if [a + b

Javascript

function checkValidity[a, b, c]

{

    if [a + b =b: return True else: return False # Reading Three Sides side_a = float[input['Enter length of side a: ']] side_b = float[input['Enter length of side b: ']] side_c = float[input['Enter ...
