from an external point p two tangents pa and pb are drawn to the circle with centre o if c is the mid point of chord ab prove pc passes throigh the centre o of the circle
​

Answer 1

Step-by-step explanation:

In this particular type of question we need to draw a diagram to develop a clear picture of what we have to do to prove OP as the perpendicular bisector of AB. First we have to prove triangle PAC and triangle PBC congruent and then using CPCT (Corresponding Parts of Congruent Triangles) to prove OP as the bisector of AB. Further we need to prove angle ACB equal to angle PCB equal to 90∘ to get the desired
