You need something more, unless you are talking about a right triangle (since you'd then know an angle).

we have to know more about one angle so that we can use the sine law or cosine law to find the third side. If it is a right triangle, we use Pythagorean theorem. If it is an isoceles one, the third side is equal to the min value of the first two sides. If it is an equilateral one, the third side is equal to both of the first two sides

For a right angled triangle use the Pythagoras Theorem, if it is not, and you can obtain some of the angles, you can use the cosine rule.

Pythagoras theorum. The square of the hypotenuse (long edge)equals the sum of the squares on the other two sides. It doesn't matter which one is missing, you can use this to find it.
