Yes, that's what makes them congruent!
The two quadrilaterals are squares.
It can have two congruent sides but does not have to.
In short, no. Similar shapes are shapes in which all corresponding angles congruent regardless of the length of the sides. Congruent shapes have congruent corresponding angles and corresponding sides. In effect congruent shapes is a special condition of similar shapes.
Rhombus
A square.
Since by definition corresponding sides of congruent shapes have the same length, the answer is 1.

No you cant
It is a rhombus.
Congruent means that two shapes are the same size and shape. When two shapes are congruent, all corresponding sides and angles are equal.
You can have two shapes - a small one and a big one - whose angles are congruent but the sides are not. In that case the shapes are not congruent but similar.
Yes, that's what makes them congruent!
