Definition
A right angle is an angle that measures exactly 90 degrees.
Description
Right angles are fundamental in geometry and are often used as a reference for measuring other angles. They are commonly found in various geometric shapes and real-world structures, such as squares, rectangles, and buildings. In real-world applications, right angles are essential in construction and design, where they ensure that elements are perpendicular and aligned correctly. In education, understanding right angles is crucial for learning about perpendicularity and the properties of geometric figures, forming a basis for more advanced mathematical concepts.
