Tangent of a circle is a line which touches the circle at a point from outside the circle.
Given a tangent to a circle through a point outside the circle.
We have to draw a tangent to a circle from point outside the circle.
Tangent of a circle is a line which touches the circle at a point from outside the circle.. The point at which tangent touches the circle is known as point of contact.The radius of the circle and tangent are perprndicukar to each other at the point of contact. There cannot be any tangent to the circle through a point inside the circle. There can be one tangent to a point on the circle. The steps of drawing a tangent to a circle are as under:
1) Draw a circle with the radius neede with center O.
2) Join center of the circle O and any point P on the circle OP is the radius of the circle.
3) Draw a line perpendicular to radius OP through point P which is the intersection point of tangent and circle.
This line is the tangent to the circle at P.
