In this mini-lesson, you will learn about the definition of an angle, degree and angle measure. An angle is the set of points i.e. the union of two rays having common endpoints. 1° is equal to 1/360 of a complete rotation of a ray about its endpoints i.e.1° = 1/360. It also explains with the help of video, about the classification of angles i.e. acute angle, right angle, obtuse angle, straight angles and adjacent angles etc. Further it explains using some examples with solution that angles whose measures have a sum of 90° are complementary angles and if the sum is 180° then the angles are supplementary. In addition, you will learn with explanations that if two angles share a common vertex and whose sides form two lines are vertex angles. You will also become familiar with the basics of the linear pairs of angles.
