right angle
an angle that measures 90 degrees
A right angle is an angle that measures exactly 90 degrees. It is formed when the perpendicular lines or rays intersect at a point. The symbol used to represent a right angle is a small square placed in the corner of the angle. Right angles are commonly found in geometric shapes such as squares, rectangles, and triangles. In geometry, right angles play an important role when measuring angles and determining the properties of different shapes. They are also widely used in various fields such as construction, engineering, and architecture, where accurate measurements and angles are crucial for designing and building structures.
