An angle is an amount of rotation of a half-line (or ray) in a plane about its end point from an initial position to a terminal position. The important terms are: Measurement of angle, Positive and Negative angles, Lines at right angles, Quadr..

Which of the figures have congruent angles? => Figure (a) and Figure (d) or Figure (a) and Figure (b) or Figure (b) and Figure (c) or Figure (c) and Figure (d)..

Reflex Angle : An angle whose measure is more than 180 o and less than 360 o is called a reflex angle..

When two straight lines meet at a common point, they form an angle. and are called arms of the angle BAC. The point 'A' is called the vertex. The angle formed by the two rays AB and AC is denoted by the symbol BAC. If there is only one angle at A, the..

Definition - When two straight lines meet at a point they form an angle. The point at which the arms meet (O) is known as the vertex of the angle. The amount of turning from one arm (OA) to other (OB) is called the measure of the angle ( AOB) and written as m AOB. An h..

Fig.(i) Fig.(ii) Fig.(iii) Let OA and OB two half lines with common end point O. The half lines OA and OB are the sides of an angle and the point O is the vertex of the angle. An angle is an amount of rotation..
