Conditions for a Valid Triangle
The length of any two sides added together must be more than the length of the third side in order for a triangle to be considered valid. In other words, for three side lengths a, b, and c to form a triangle, the conditions listed below must be true:
a + b > c
a + c > b
b + c > a
JavaScript Program to Count the Number of Possible Triangles in Array
Triangles are basic geometric figures with three sides and three angles. Finding the number of triangles that can be created from a given set of side lengths is a frequent challenge in computational programming. In this article, we’ll see how to use a JavaScript array to calculate the total number of triangles that could exist. Before we proceed, we will understand the prerequisites for a legitimate triangle and offer a methodical solution to this issue.
