How often does the letter e occur in:
Angle is discussed here in details. In our daily life we come across different objects having two arms hinged at a point. For example, hands of a clock, two arms of a divider, and two sharp edges of a scissors are all hinged at a point and thus are inclined to each other. This inclination between two arms is known as angle.
When two rays have a common end point they from an angle. In this figure two rays OA and OB have a common end point O. So they form an angle AOB. The common end point is called the Vertex and rays OA and OB are the arms of the angle.
In the above figure, AOB is angle whose two arms are the rays OB and OA. The symbol for an angle is < and angle AOB can be written as <AOB. Every angle has a measure. The unit of measurement of an angle is degree (°). In a figure the measure of an angle is generally written between the arms of the angle, close to the vertex.
Always remember, while naming the angle, the vertex is always in the centre.
