    • TANGENTA tangent to a circle is aline that intersects thecircle at only one point A B
    • A tangent isperpendicularto the radiusof a circle
    • THEOREMTHE LENGTH OF TWO TRIANGLES TO A CIRCLEFROM A EXTERNA POINT A EQUA A THEY N L RE L NDA EQUA INCLINED TO THE LINE SEGMENT RE LLYJOINING THE CENTRE A THA POINT T T
