When horizontal and vertical lines intersect, they form a specific type of angle known as a right angle. This angle measures exactly 90 degrees. In geometry, a right angle is characterized by its perpendicular orientation, where one line is perfectly horizontal while the other is vertical. The resulting intersection creates four right angles at the point they meet, each measuring 90 degrees. This fundamental concept is essential in various applications, including architecture and design, and is vital for understanding how shapes are structured in cosmetology practices, such as when analyzing the geometric aspects of hairstyles or haircuts.
