Problem I. 113. (October 2005)

I. 113. A cardioid is obtained as the locus of a point P on the rim of a circle l that rolls without skidding along the circumference of another circle k with the same radius. (See Figure.)

Construct a cardioid using the ``trace'' feature of the program Euklides. The final worksheet in Euklides's own file format (I113.euk) is to be submitted.
