A 90-degree angle has an internal angle equivalent to 90 degrees and forms a perfect L shape. It is also known as a right angle.

A right angle has 90 degrees. Angles are measured on a scale from 0 to 360 degrees. Right angles represent one-fourth of a full 360-degree revolution.

A 360 degree angle is called a full circle. Angles can be measured from zero degrees all the way to 360 degrees because 360 degrees is one full rotation.

A 180-degree angle is called a straight angle. Angles that are exactly 90 degrees are called right angles, while those that are between 0 and 90 degrees are called acute. Angles that are between 90 and 180 degrees are considered obtuse.

A 45-degree angle looks like the bisection of a right angle. If one constructs a right angle by drawing one axis horizontally and the other axis vertically, a 45-degree angle is halfway between a flat slope and a vertical slope.

A zero degree angle appears as a straight line that travels from the point of inception to the right or positive side of a number line. If the line travels both left and right from the point of inception, it is considered a 180 degree angle or straight angle.

There is no direct way to convert angular degrees to inches because they are units for different properties, or as it's often stated, they are "apples and oranges." However, knowing the measurement of an angle in degrees along with other information can sometimes provid...
