They are quadrilateral shapes whose opposite sides are parallel. In a parallelogram, one pairs of parallel sides may be of a different length to the other pair; in a rhombus all four are the same length.
Since by definition corresponding sides of congruent shapes have the same length, the answer is 1.
No, a parallelogram cannot be a hexagon. A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length, while a hexagon is a polygon with six sides. These are two different shapes with different numbers of sides.
No, octagons just have to be closed shapes with eight sides - the sides do not have to be of equal length.

Both shapes have 4 sides, two pairs equal in length. In a parallelogram the equal length sides are opposite each other. In a kite the equal length sides are adjacent.
If you mean 'Irregular' and 'Regular shapes' then this is the answer. A regular shape is a shape that has E.g. 4 sides that are the same length but and irregular shape is one that has the same amount of sides, just different lengths.
They are quadrilateral shapes whose opposite sides are parallel. In a parallelogram, one pairs of parallel sides may be of a different length to the other pair; in a rhombus all four are the same length.
Since by definition corresponding sides of congruent shapes have the same length, the answer is 1.
A square will have 4 sides that are all the same length, and 4 angles that are 90 degrees each. Other shapes will have 4 sides, but they may be of different lengths. Other shapes will have 4 equal sides, but not 4 angles of 90 degrees.
No, a parallelogram cannot be a hexagon. A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length, while a hexagon is a polygon with six sides. These are two different shapes with different numbers of sides.
A rhombus.
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.
