Use diameter form to find equation of circle. Apply the theorem of Converse of Angle in Semi-circle we can see that P Q R S are concyclic with PS as diameter. Now you can identify the.
In geometry a circle is a two-dimensional round shaped figure where all the points on the surface of the circle are equidistant from the centre point c.
And that is the Standard Form for the equation of a circle. Since the point of tangency is given thats the point to use. X - h 2 y - k 2 r 2. Input circle equation in standard or in general form.
