Right angle - Wikipedia
In geometry and trigonometry, a right angle is an angle of exactly 90 degrees or 2 radians [1] corresponding to a quarter turn. [2] If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles. [3]

Right Angle – Definition with Examples - Math Monks
A right angle, also known as a 90-degree angle, is defined as an angle that measures exactly 90°. It is formed when two straight lines that are perpendicular to each other intersect at a point.
Right angle - Math.net
A right angle is an angle that measures 90 degrees. In geometry, a square is typically drawn at the vertex of an angle to indicate it is a right angle. If the intersection of two lines forms a right angle, the lines are said to be perpendicular.
