angle
the opening between 2 rays that share the same endpoint
An angle is a geometric figure formed by two rays or line segments that share a common endpoint. The endpoint is called the vertex and the two rays or line segments are called the sides or legs of the angle.
Angles are measured in units called degrees or radians. A degree is 1/360th of a full circle, and a radian is the measure of an angle that, when the radius of a circle is wrapped around it, covers an arc length equal to the radius.
There are various types of angles, such as acute, right, obtuse, and straight angles. An acute angle is an angle that measures less than 90 degrees, a right angle measures exactly 90 degrees, an obtuse angle measures more than 90 degrees but less than 180 degrees, and a straight angle measures exactly 180 degrees.
Angles can be used to describe the orientation of objects, the direction of motion, and the shape of geometric figures. They are important in many fields, including mathematics, physics, engineering, and navigation.
