Yes.
They are said to be similar but not congruent triangles.
Such triangles are similar.
If the 3 sides are proportional by ratio and the angles remain the same then the two triangles are similar
Yes, the corresponding sides of similar triangles have proportional lengths. This means that the ratios of the lengths of corresponding sides are equal. For example, if two triangles are similar, the ratio of the lengths of one triangle's sides to the lengths of the other triangle's corresponding sides will be the same across all three pairs of sides. This property is fundamental in solving problems related to similar triangles.

Yes. You can even have two triangles with two pairs of sides that are the SAME measure without the triangles being similar.
similar
Proportional.
Yes, if the three corresponding sides of one triangle are proportional to the three sides of another triangle, then the triangles are similar. This is known as the Side-Side-Side (SSS) similarity criterion. When the sides are in proportion, it ensures that the angles of the triangles are also equal, thus confirming their similarity. Similar triangles maintain the same shape but may differ in size.
