Congruent figures are similar - in sides as well as angles. Corresonding angles of similar figures congruent but their sides are not. The sides are all in some fixed ratio. [If that ratio is 1, the figures are congruent.]
Congruent Figures has equal sides, angles, shape and size.
Corresponding Sides
... similar.
The lengths of the sides need not be congruent. For example, consider a square and a rectangle.

yes they are because they have congruent sides
They are said to be congruent
They are similar.
