angle
two rays with a common endpoint
An angle is a figure formed by two rays originating from a common endpoint called vertex. It can be measured in degrees or radians and is denoted by the symbol ∠. The most commonly known angle is the right angle, which measures 90 degrees.
Angles can be classified based on their measure as acute angles (less than 90 degrees), obtuse angles (greater than 90 degrees but less than 180 degrees), right angles (exactly 90 degrees), straight angles (exactly 180 degrees) and reflex angles (greater than 180 degrees but less than 360 degrees).
Angles can also be complementary (the sum of their measures equals 90 degrees), supplementary (the sum of their measures equals 180 degrees), adjacent (share a common vertex and a common side), vertical (opposite angles formed when two lines intersect), and congruent (having the same measure).
Angles are used in various areas of mathematics, science, engineering, and technology. They are used to measure directions, determine distances, analyze forces and motions, and solve problems in trigonometry.
