The question asks about four sides and 2 perpendicular sides. That makes 6 sides in all. So it is a hexagon with either only one right angle, or two sides that are mutually perpendicular.
Square
a triangle with 2 sides
well a regular pentagon has 5 equal sides, so it has two equal sides? But I can also create a pentagon with exactly 2 equal sides? Not sure what you are looking for? Well, any 5 sided shape is a pentagon. And like the above states, a pentagon with exactly 2 equal sides can be created. So, the is a pentagon.

Square
Im pretty sure that's a right triangle.
A square has 4 right angles, and 2 pairs of equal, perpendicular sides.
A quadrilateral is any shape that has for sides. A trapezoid is any shape that has four sides AND exactly 2 sides that are parallel to each other.
It could be a trapezoid having 2 right angles, an obtuse angle and an acute angle
A rhomus has 2 parallel sides and all sides are the same length. It may or may not have perpendicular sides; if perpendicular it is a special case of a rhombus and is called a square
A regular pentagon has zero perpendicular sides. If it is irregular, it could have as many as 2 or 4 perpendicular sides.
