If two sides of a triangle are given, suppose 10 and 15, is third angle is always greater than 5 and less than 25, or it can be any other measurement, like 3, 4, 30?

Angle or side?

As Leaderboard hinted at, the â€śtriangle inequality theoremâ€ť states that the third side of a triangle must be greater than the difference of the two other sides, and less than their sum.

So, concretely, a triangle with two sides (not angles) of 10 and 15 must have a third side that is greater than 5 (not 5, but it can be a 5.01), or a length that is less than 25 (24.99â€¦ or less).
