A ladder placed against a building is a real life example of a linear pair. Two angles are considered a linear pair if each of the angles are adjacent to one another and these two unshared rays form a line. The ladder would form one line, while a building or wall would form another line.
Know MoreA linear pair of angles are sometimes simply called supplementary angles. Supplementary angles are angles whose sum equals 180 degrees.
Linear pairs can also be seen in parking lots with diagonally crossing lines running adjacent to a center straight line. While parking lot spaces marked by vertical lines intersecting horizontal lines would create angles, these angles would not be considered adjacent angles due to the sum of their degrees not equaling 180.
Although a linear pair of angles is often used interchangeably to mean supplementary angles, they are not exactly the same. While all supplementary angles do not have to be adjacent, all linear pairs must have adjacent angles that form a line.
Adjacent angles are two angles in a plane that share both a common vertex and a common side, but these sides do not overlap. Other types of angles include vertical angles and congruent angles.

The sharply angled, pointed shape of a slice of pizza is another common example. One famous acute angle in pop culture occurs when the character Pac-Man opens his mouth to devour the dots.
Full Answer >Real-life examples of linear equations include distance and rate problems, pricing problems, calculating dimensions and mixing different percentages of solutions. One application of linear equations is illustrated in finding the time it takes for two cars moving toward each other at different speeds to reach the same point. Another example is estimating how much a shirt on sale for $20 and marked down by 35 percent cost before the sale.
Full Answer >Everyday budgeting and other financial issues often use linear equations. Linear equations involve two values that change according to a consistent pattern.
Full Answer >Geysers erupt when an underground reservoir becomes superheated by subterranean magma, building up enough pressure to reach temperatures well above the boiling point. When the water works its way to the surface, it releases the pressure, causing a sudden, massive boilover. This ejects all the water in the reservoir to the surface in a boiling plume, creating a geyser.
