What Is a Real-Life Example of Perpendicular Lines? – The intersection of two city roads is a good example of perpendicular lines in real life. When one road crosses another, the two streets meet at an angle and form a cross pattern. On a two-dimensional plane, perpendicular lines make 90-degree angles, or right angles, with each other.
Graph paper, plaid patterns on fabric, square lines of floor tiles, lines of mortar on brick walls, the intersecting lines of a Christian cross, metal rods on the cooking surface of a barbecue grill, wooden beams in a house wall, and the designs on country flags such as Norway, the United Kingdom, Switzerland, Greece, Denmark, and Finland are all examples of perpendicular lines in the real world. In many real-world shapes, perpendicular lines form the corners of squares and rectangles.
At their intersection point, perpendicular lines generate four right angles, totaling 360 degrees. Perpendicular lines also make up one of the right triangle’s angles. Students learn to compute the slopes of lines on graph paper using perpendicular lines in algebra and geometry.
Parallel lines are distinct from perpendicular lines in that they never cross. Railroad tracks, stripes on the American flag, power lines draped between poles, lines on composition paper, and plugs at the ends of electrical cords are all instances of parallel lines in the real world.
