Why must there be 20 hexagons and 12 pentagons in a soccer ball?

There are actually many different types of soccer balls, they don't have to have those exact specifications. Though commonly that is what you see sold today. The shape created by 20 hexagons and 12 pentagons is a spherical polyhedron, which has the dynamics to withstand pressure displacement. The shape is also considered to be the basics of the dome, with its carbon like structure.
So the short answer is the shape created by your specifications makes the ball dynamically sound, though those are not the only dynamically sound specifications for soccer balls.

What is the number of pentagons and hexagons on an official soccer ball?
Soccer balls have different patterns, but if you have both regular pentagons and regular hexagons it must have 12 pentagons and 20 hexagons.
Do the pentagons and the hexagons on its surface help the soccer ball do anything?
Yes, in theory: the number of panels a ball has determines the movement and spin a player can create due to reduced drag from less edges and vertices. The size and weight of an official ball must comply with FIFA guidelines. The current World Cup match ball (adidas' Jabulani) has 8 panels, none of which are hexagons or pentagons. The materials used are also in constant evolution: the Jabulani is not made of traditional leather, but of textured ethylene-vynil acetate (EVA).

The characteristics of triangles squares rectangles parallelograms quadrilaterals pentagons hexagons and octogons?
Squares, rectangles, and parallelograms all fall under the category of "quadrilateral" simply because they all have four sides; however, quadrilaterals must also be two-dimensional, and all of its sides must be straight. Squares must have four equilateral sides--with opposite sides parallel to each other-- and each angle must be a right angle (90 degrees). Rectangles are like squares in that each angle must be a right angle, and opposite sides must be parallel, but all four sides need not be equal to each other in length; rather, only opposite sides are equal in length. Parallelograms must have opposite sides that are equal in length and parallel to each other, as well as opposite angles that are equal to each other, but these angles are not right angles. Triangles, pentagons, hexagons, and octagons all fall under the category of "polygon" because they are two-dimensional figures made of straight lines, but do not have four sides like quadrilaterals. Triangles must have three sides and three angles that add up to 180 degrees. Pentagons have five sides, hexagons have six sides, and octagons have eight sides.
