Parallel lines exist everywhere in everyday life, including on the sides of a piece of paper and the way that the shelves of a bookcase are positioned. Parallel lines are two or more lines that when drawn out infinitely long never intersect.
Know MoreFor example, a rectangle or a square is made up of four sides, where the opposite sides are parallel to each other. In a trapezoid, two of the sides are parallel where as the other two are slanted towards each other and, therefore, are not. Because of the many shapes in which parallel lines can be found, they have several applications in everyday objects.
In geometry, parallel lines can be identified and drawn by using the concept of slope, or the lines inclination with respect to the x and y axis. Two lines with the same slope do not intersect and are considered parallel. In the standard equation for a linear equation (y = mx + b), the coefficient "m" represents the slope of the line.
On a standard Cartesian plane, there are infinitely many parallel lines that can be drawn with respect to one another. On the contrary, equations that intersect at a 90-degree, or right angle, are considered perpendicular.

Full Answer >Two examples of parallelograms seen in everyday life are the United States Postal Service symbol and the intricate structures on the neck of a guitar. A parallelogram is a quadrilateral with both pairs of opposite sides being parallel.
Full Answer >In real life, there are many different applications of geometry including everyday uses such as the "stop sign," which is an octagon shape. The shape, volume, location, surface area and various other physical properties are central to the objects around people.
Full Answer >The Pythagorean Theorem can be used in any real life scenario that involves a right triangle having two sides with known lengths. In a scenario where a certain section of a wall needs to be painted, the Pythagorean Theorem can be used to calculate the length of the ladder needed if the height of the wall and the distance of the base of the ladder from the wall are known.
