No
You must know that the angle between is equal or that also the third sides are in the same proportion of the other

If that is all you know about the two triangles, then, no, you cannot say the two triangles are similar. For example, given the two sides of two different triangles as follows:
Triangle A: Side a = 10, side b = 5, side c can be any value between 5 and 15
Triangle B: side a = 20, side b = 10, side c can be any value between 10 and 30
The sides a and b of the two triangles are proportional, but side c is not necessarily proportional between the two triangles. If a is 6 in triangle A, then A is an acute triangle and if a is 29 in triangle B, then B is an obtuse triangle. Two of the three sides would be proportional, but the triangles would not be similar.
