There are many different types of quadrilaterals: squares, rectangles, rhombuses, trapezoids, parallelograms and kites. A quadrilateral defined as a closed shape (polygon) that consists of exactly four straight lines.
There are only three properties that every quadrilateral shares. They must all have four sides, four vertices and four internal angles with a total sum of 360 degrees.
The simplest type of quadrilateral is the square. A square can be any size, but all of its sides must be the same length, and both sets of opposite sides must be parallel to each other. The internal angles must also be exactly 90 degrees.
A rectangle is similar to a square in that opposite sides are parallel and equal in length to each other, but not all sides must be the same shape. A square fulfills all these conditions and is a special type of rectangle.
The rhombus shares almost all the properties of a square, with four equal sides and parallel opposite sides. However, while opposite angles need to be equal, angles do not need to be 90 degrees.
Trapezoids and kites are two quadrilaterals where the opposite sides do not need to be parallel. They are the most general quadrilaterals, and every other quadrilateral fits the definition for either a trapezoid or kite.

Full Answer >Examples of cylinders in everyday life include food tins, drink cans, candles, toilet paper rolls, cups, aerosol cans, flower vases, test tubes, fire extinguishers, plant containers, salt shakers and pencil holders. Other examples include chalk, lipstick containers, cooking gas cylinders, toothpick holders, thermos flasks and petroleum jelly containers.
Full Answer >Real life examples of parallelograms include tables, desks, arrangements of streets on a map, boxes, building blocks, paper and the Dockland office building in Hamburg, Germany. A parallelogram is a two-dimensional shape that has opposite sides that are equal in length and parallel to each other, and opposite angles that are equal. Rectangles, squares and rhombuses are all parallelograms, so any object that has one of these shapes is a parallelogram.
Full Answer >When a pitcher throws a baseball, it follows a parabolic path, providing a real life example of the graph of a quadratic equation. The parabolic function predicts if the ball arrives in the batting range for the particular hitter and the time between it leaving the pitcher's hand and crossing the plate. There are many real life examples of such shapes ranging from video games to engineering.
