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.

The ratio between corresponding sides or angles of similar triangles are equal
Corresponding Sides
... similar.
Both are polygons; plane figures with multiple sides, the pentagon having five angles and five sides; the hexagon having six angles and six sides.
The lengths of the sides need not be congruent. For example, consider a square and a rectangle.
squares
yes they are because they have congruent sides
They are said to be congruent
