what is angle? (essay) fast

Answer 1

Introduction to Angles We begin our study of angles by learning what they are, how to name them, and ways in which angles can be classified. Angle An angle is formed when two rays meet at a common endpoint, or vertex. The two sides of the angle are the rays, and the point that unites them is called the vertex. Classifications of Angles Angles can be measured in degrees or radians. For the time being, we will strictly talk about angles in terms of their degree measure. The symbol for degrees is °. Angles can measure from 0° up to 360°. Angles with no measure are called zero angles, while angles of 360° are full rotations. 1-Right Angle,2-Acute Angle,3-Obtuse Angle,4-Straight Angle,5-Reflex Angle(The reflex angle is the larger angle. It is more than 180° but less than 360°)
