angles

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, Quadrants, ..

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 point they form an 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..
