Tangents
If a line through a point on a circle is perpendicular to the radius through that point, then the line is a tangent to the circle.
The tangent at a point on a circle is perpendicular to the radius through that point.
Each of the two angles made by a tangent to a circle and a chord through the point of contact is equal to an angle in the segment on the other side of the chord.
The lengths of the tangents from a point outside a circle are equal.
The bisectors of the three angles of a triangle intersect at a point.

The bisectors of the three angles of a triangle intersect at a point.
Properties of triangle
The sum of the length of any two sides of a triangle is greater than the third side.
The sum of the measures of three angles of a triangle is 180 degree.
Median : The line segment with mid point of any one side of a triangle with opposite vertex as end points is called a median of the triangle.
Altitude: An altitude of a triangle is the perpendicular line segment from a vertex to its opposite sides.

Basic concepts of circles
(1)A line segment with two end points on circle is a chord of the circle.
(2) The longest chord of a circle is its diameter which contain its centre.
(3) The radius of a circle is the distance between the centre and any point on the circle.
(4) The length around the circle is called Circumference.
