Intersecting lines that form a right angle are defined as ___. A. perpendicular B. parallel C. skew D. planes

A fun fact about perpendicular lines is that they create a right angle (90 degrees) at their intersection! These lines show up everywhere in our daily lives, from the corners of your favorite books to the grid-like patterns of city streets. Next time you're on a walk, take a moment to notice how many perpendicular lines you see! Perpendicular lines don't just stop at geometry; they have real-world applications in fields like architecture and engineering. Ensuring elements are perpendicular can mean the difference between a sturdy building and an unstable one! So whether it's the walls of a house or the framework of a bridge, those right angles are key to structural integrity.
