Check whether Quadrilateral is valid or not if angles are given

0 0 3 minutes read

Given four integers A, B, C and D which represents the four angles of a Quadrilateral in degrees. The task is to check whether the given quadrilateral is valid or not.

Examples:

Input: A = 80, B = 70, C = 100, D=110
Output: Valid

Input: A = 70, B = 80, C = 130, D=60
Output: Invalid

Approach:
A Quadrilateral is valid if the sum of the four angles is equal to 360 degrees.

Below is the implementation of the above approach:

C++

// C++ program to check if a given 
// quadrilateral is valid or not
#include <bits/stdc++.h>
using namespace std;
 
// Function to check if a given 
// quadrilateral is valid or not
bool Valid(int a, int b, int c, int d)
{
    // Check condition
    if (a + b + c + d == 360)
        return true;
     
    return false;
}
 
// Driver code
int main()
{
    int a = 80, b = 70, c = 100, d = 110;
 
    if (Valid(a, b, c, d))
        cout << "Valid quadrilateral";
    else
        cout << "Invalid quadrilateral";
         
    return 0;
}

Java

// Java program to check if a given 
// quadrilateral is valid or not 
class GFG
{
     
// Function to check if a given 
// quadrilateral is valid or not 
public static int Valid(int a, int b, 
                        int c, int d) 
{ 
    // Check condition 
    if (a + b + c + d == 360) 
        return 1; 
     
    return 0; 
} 
 
// Driver code 
public static void main (String[] args) 
{
    int a = 80, b = 70, c = 100, d = 110; 
     
    if (Valid(a, b, c, d) == 1) 
        System.out.println("Valid quadrilateral"); 
    else
        System.out.println("Invalid quadrilateral"); 
} 
}

    return False;
 
 
# Driver code
a = 80; b = 70; c = 100; d = 110;
 
if (Valid(a, b, c, d)):
    print("Valid quadrilateral");
else:
    print("Invalid quadrilateral");
