Analyze the three cases of the relationship between a line and a circle. Complete the table based on the given conditions (OH > R, OH = R, OH < R), describing the number of common points and the name of the line 'a'.

Analysis of Cases:

We are given a line 'a' and a circle with center O and radius R. We are also given that OH is perpendicular to line 'a', and H is a point on line 'a'. The relationship between the distance from the center to the line (OH) and the radius (R) determines how the line and circle interact.

Answer: The table above summarizes the analysis.
