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 angle is measured in degrees,..

"The point of concurrency of the angle bisectors of the angles of triangle, is called the incentre". It is abbreviated as 'I'. To determine the incentre of a triangle, it is just sufficient to find the point of intersection of its two angles. The third angle bisector is bound to pass thro..
Some Important Definitions
Median - In a triangle, a line joining the midpoint of a side to the opposite vertex is called a median. AD is a median of ABC. In any triangle, it can be proved that all the three medians meet at a point. The point where the three medians meet is called the Centroid of the triangle. The ..
