Rhombus
Parallelogram.
It is not possible to have five perpendicular sides; four or eight, but not five. A shape with five equal sides is a pentagon.
-- four equal sides -- opposite sides are parallel -- opposite angles are congruent -- diagonals are perpendicular
yes they are. a rhombus has four equal sides, and can or can't have right angles.

A square has four perpendicular sides.

No, a square has four perpendicular sides.
No. Each of its four sides is perpendicular to two other sides.
a rhombus
A regular pentagon does not have any perpendicular sides. A pentagon is made up of five sides. An irregular pentagon which has sides that are not equal may have a perpendicular side.
A square must have four sides of equal length, and have a right-angle (90 degrees) in each of the four corners.
