TYPE 13: Find the intersection of a line and an arc
when 2 points are known on the line, and
the arc’s center and radius are known

If the information you know about the line and arc correspond to Type 13,
then select the 13 soft key. The screen will then show:

Input the known data in the same way you would program an event. When
all of the data is entered, the solution (or solutions if there are more than
one) will be shown on the left side of the information area.
There are often multiple solutions for geometry problems. For example, in
the Type 13 example above, a line will often intersect an arc or circle in two
