What is 45 degree angle?

A 45-degree angle is an angle that measures exactly 45 degrees, which is halfway between a straight angle (180 degrees) and a right angle (90 degrees). It can be represented by a diagonal line dividing a square into two equal parts. In geometry, a 45-degree angle is often used to bisect right angles or to create 45-45-90 triangles, which have sides that are in the ratio of 1:1:sqrt(2). It is also commonly used in trigonometry and navigation to determine the direction of travel or the bearing of an object.
