In this video, the instructor shows how to find the **equation** of a **circle** given its center point and a tangent line to it. To do this, take a graph and plot the given point and the tangent on that graph. Now, from the center of the **circle**, measure the perpendicular distance to the tangent line. This gives us the radius of the **circle**. Using the center point and the radius, you can find the ...
