Question

input three angles and determine if they form a triangle or not

Answer 1

Explanation:

: 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++

// C++ program to check if three

// sides form a triangle or not

#include<bits/stdc++.h>

using namespace std;

// function to check if three sider

// form a triangle or not

bool checkValidity(int a, int b, int c)

{

// check condition

if (a + b <= c || a + c <= b || b + c <= a)

return false;

else

return true;

}

// Driver function

int main()

{

int a = 7, b = 10, c = 5;

if (checkValidity(a, b, c))

cout << "Valid";

Answer 2

Explanation:

if the sum of 3 angles is 180 then it is a triangle.

such that all 3 angles should be greater then 0.

i.e no angle should be zero.
