#### Construction of Tangents to a Circle

We have already studied in Chapter 10 of Chapter 10 that if a point is inside a circle, there cannot be a tangent to the circle through this point. However, if a point is on a circle, the circle at this point has only one tangent and is perpendicular to the radius passing through this point. So if we want to draw a tangent to a point on a circle, simply draw a radius through this point and draw a line perpendicular to this radius through this point and it will be the tangent required to the point. We have also seen that if the point is outside the circle, the circle will have two tangents from this point. In this section, we will learn how to construct a tangent from a point outside it to a circle.

##### Tangent to a Circle

We are given a circle with center O and a point P outside it. We have to construct two tangent lines of P.
construction phase:

1. Join PO and Bisect. M is the midpoint of PO.
2. Draw a circle, taking M as the center and MO as the radius. Divide the given circle at the points Q and R.
3. Join PQ and PR. Then PQ and PR are the two tangents, which we are trying to make. Now we will learn how this complete construction works. Join OQ. Then ic PQO is an angle in the semicircle and hence O PQO = 90 °
4. Now, we can say that PQ, OQ.
5. Since OQ is a radius of a given circle, PQ must be tangent to the circle. Similarly, PR is also a tangent to the circle.
###### Centre of Circle is required

If the center of the circle is not given, you can locate its center by first taking two non-parallel cords and then finding the point of intersection of their perpendicular bisector. You can then proceed to draw the tangent in the given circle.
