make an angle. The two lines are called the sides of the angle, and they meet at a point. A flat surface (called a plane) also forms an angle when it...

A right angle is an angle with a measurement of 90 degrees. When two lines cross each other so that all the angles have the same size, the result is four...

An acute angle ("acute" meaning "small") is an angle smaller than a right angle. The range of an acute angle is between 0 and 90 degrees, or between 0...

In mathematics, a degree is a common way to measure plane angle. It is written with the symbol ∘ {\displaystyle ^{\circ }} , where 360 ∘ {\displaystyle...

An obtuse angle is an angle of greater than 90° and less than 180°. It is bigger than an acute angle. It is smaller than a straight angle, which measures...
