What is a Triangle?
a plane figure with three straight sides and three angles.
How to determine?
If you are referring to a triangle with known side lengths of 3 and 5, then all we can say about the length of the third side is that it must be more than 3 and less than 5:
If you imagine the two sides (lengths 3 and 5) are the hands of a clock, if the time is 12:00 with both the hands on top of each other, then the distance between the two points of the hands is 5–3 or 2 units, that is the shortest distance between the two endpoints of our clock hands. So the third side of the triangle must be more than 2 units long.
