The center point x pops up and is briefly visible but when i move the cursor to select that point it disappears.
We proceed in several steps use problem #1 to construct the point c such that bc forms a diameter of the circle i. Use the midpoint formula to find the midpoint of the line segment. When you graph a circle, triangle, or line segment by using coordinate axes, then you can all you need to find these middles are the coordinates of some crucial other points on the respective figures. So how do we find an equation in terms of r and h, k, and x and y that describes all these points?
