Not always, sometimes two obtuse triangles are similar and sometimes they are not similar.

The triangles are similar, but not necessarily congruent.
Yes, similar triangles are congruent because in order to be congruent they must first be equal. Which in turn is the definition of a similar triangle. A triangle equal in angle measurements and/or side lengths. So, yes.
90 degree triangles are always similar.
They are said to be similar but not congruent triangles.
Pairs of triangles, in general, do not have to be similar.
They are similar triangles.
Two equilateral triangles are always similar!
There are no ratios that can be used for triangles that are not similar.

for two similar triangles , their corresponding angles are equal.
If the angles of two triangles are equal the triangles are similar. AAA If you have three angles on both triangles these must be equal for the triangles to be similar. SAS If you have an angle between two sides and the length of the sides and the angle are the same on both triangles, then the triangles are similar. And SSS If you know the three sides
