Right angle Right angle In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles. The term is a calque of Latin "angulus rectus"; here "rectus" means "upright", referring to the vertical perpendicular to a horizontal base line. Closely related and important geometrical concepts are perpendicular lines, meaning lines that form right angles at their point of intersection, and orthogonality, which is the property of forming right angles, usually applied
While(1 Is Less Than 2) 3.5/5 stars. Rolling Stone, however, was more critical of the album stating "Deadmau5 has turned from an electro-house polymath into the world's most unnecessary Nine Inch Nails tribute act" giving it 2 stars out of 5.
