angles are congruent. That is sufficient to force the corresponding sides to be proportional - which is the other definition of similarity.

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.
True. With similar triangles the corresponding angles are equal.
for two similar triangles , their corresponding angles are equal.
They are two triangles whose corresponding sides and angles are the same.
It is given that two triangles are similar. So that the ratio of their corresponding sides are equal. If you draw altitudes from the same vertex to both triangles, then they would divide the original triangles into two triangles which are similar to the originals and to each other. So the altitudes, as sides of the similar triangles, will have the same ratio as any pair of corresponding sides of the original triangles.
Yes.
The ratio between corresponding sides or angles of similar triangles are equal
