Using side lengths only could the triangles be similar?

No

Step-by-step explanation:

For triangles to be similar there must be a proportion between their measurements.

That is, for example if from one triangle to another one side doubled, all other sides must also double.

The triangle side on the left sides measure 1.5, 1 and 2.

In the right triangle the sides measure 0.5, 1 and 1.5

There is no proportion factor that serves to convert all the measures of the first triangle to those of the second triangle.

So the triangles are not similar.
