Triangles are congruent if all three sides in one triangle are congruent to the corresponding sides in the other.When two triangles have corresponding sides with identical ratios, the triangles are similar.Of course if triangles are congruent, they are also similar.

The term for two triangles that are congruent after a dilation is similar.

No. If they are congruent they must be similar. The reverse is not true, though.

The geometrical figures, including isosceles triangles, are congruent if they are identical in shape and size. If they are of the same shape but not of the same size, then they are similar triangles. For two similar triangles, there is a correspondence between their vertices such that corresponding angles are equal and the ratios of the corresponding sides are equal. Thus, not all isosceles triangles are congruent.

They're similar triangles.

No.

Yes. Similar triangles have equal corresponding angles, and so do congruent triangles.

Congruent triangles are the same because all three sides measure the same length.

All equiangular triangles are similar, but not congruent. They all have three 60 degree angles. This does not mean that they all have the same side lengths though. Therefore, they are only similar, not congruent.

Congruent

They are said to be similar but not congruent triangles.

Increasing the dimensions of the smaller of the similar triangles (if they are not already congruent) by a suitably chosen constant factor.
