  5. Wait patiently for a helper to come along.
  6. If the Helper has answered your question, remember to thank them with the Mathematics Ranks bot and close the thread with:

First of all do you know the equation of a circle.
When it appears in the form (picture), you must apply difference of squares to achieve the ideal format - i presume you must already know the equation of a circle.

some other terms
a tangent is 90 degrees to a line that is drawn through the centre (radius/diameter)
a chord connects any 2 points
a perpendicular bisector is 90 degrees to another line and cuts it right in half.
