Valid triangle edges - JavaScript
Suppose, we have three lines of length, respectively l, m and n. These three lines can only form a triangle, if the sum of any arbitrary two sides is greater than the third side.
For example, if the length of three lines is 4, 9 and 3, they cannot form a triangle because 4+3 is less than 9.
We are required to write a JavaScript function that the three numbers represents the length of three sides and checks whether they can form a triangle or not.
Example
Following is the code −
const a = 9, b = 5, c = 3;
const isValidTriangle = (a = 1, b = 1, c = 1) => {
if(!a || !b || !c){
return false;
};
const con1 = a + b > c;
const con2 = b + c > a;
const con3 = c + a > b;
return con1 && con2 && con3;
};
console.log(isValidTriangle(a, b, c));Output
Following is the output in the console −
false
