A shape with a pair of perpendicular sides is a rectangle. In a rectangle, opposite sides are equal in length, and adjacent sides meet at right angles, forming perpendicular intersections. Other shapes that also feature perpendicular sides include squares and right triangles.
No, a parallelogram does not have perpendicular sides by definition. A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. Perpendicular sides would form a right angle, which is a characteristic of rectangles, squares, and other types of quadrilaterals, but not parallelograms.
Adjacent sides are perpendicular. Opposite sides are parallel.
Aquadrilateral that is called a rectangle has by definition 4 right angles (all sides are perpendicular to their neighbors) and opposite sides that are equal in length and parallel.
Not necessarily; a rhombus has 2 pairs of opposite sides which are parallel, like the parallelogram, and its diagonals are perpendicular. (It also has all its sides of the same length.)
Parallelogram.

No, they are parallel.
Oh, dude, a rhombus actually has 4 sides with all sides being equal in length. It does have 2 pairs of parallel sides, but it also has opposite angles that are equal, not to mention it's like a tilted square. So, yeah, it's definitely not a shape that's all about parallel sides and no perpendicular ones.
rhombus
parallel
With a straight edge and making sure that its length is greater than its perpendicular height and that opposite sides are parallel to each other.
