 Hello and welcome to the session. In this session we will learn about the construction of tangents to a circle. If we are given a point inside the circle we cannot draw any tangent to this circle. If we have a point which lies on the circle then there can be only one tangent to the circle through this point. Now let's see how to construct the tangents to a circle from a point outside the circle. There is a circle with center O and a point P outside this circle. We are supposed to construct the tangents to this circle from the point P. Our first step here would be join PO and bisect it. We have joined PO and we have bisected this PO. Let's mark this point as M. Now in the next step we have taking M as the center and radius MO. We draw a circle. This circle that we have drawn by taking M as the center and radius MO intersect the given circle at points Q and R and we join. So this P, Q and PR are the required two tangents. In this session hope you have understood how to construct tangents from a point outside a circle.
