right angle
an angle that measures 90 degrees – the opening forms a square corner
A right angle is an angle that measures exactly 90 degrees. It is formed when two lines or line segments intersect perpendicularly, creating four 90-degree angles at the intersection point. The symbol for a right angle is an upside-down square shape. Right angles are commonly found in geometry, engineering, architecture, and everyday life, such as in the corners of buildings, squares, rectangles, and triangles. They are also used to determine the perpendicularity of two lines or surfaces. In trigonometry, right angles are important because they form the basis for many of the basic trigonometric ratios, such as sine, cosine, and tangent.
