Rectangle.
A square A parallelogram
A quadrilateral that has two pairs of parallel sides and two pairs of sides of equal length is called a rectangle. In a rectangle, opposite sides are both equal in length and parallel, making it a specific type of parallelogram. If all four sides are equal in length as well, it becomes a square, which is a special case of a rectangle.
A parallelogram has this description, but a parallelogram with 4 equal sides is more specifically called a rhombus.
A quadrangle with two pairs of equal sides is a square.

There can be only one pair of perpendicular lines in an isosceles triangle when it is a right angled isosceles triangle. A non right angled isosceles triangle has no pairs of perpendicular lines.
Forces that come in pairs are called action-reaction pairs. This is based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
It could be an arrowhead or kite.

Forces in pairs are called action and reaction forces, according to Newton's third law of motion. This law states that for every action, there is an equal and opposite reaction.
