Assignment 9 involves pedal triangles. Lets start with a basic pedal triangle. The pedal point P was internal.
The next figure will show P as external.
The next figure will show P on one of the sides.
The next picture shows P as rthe orthocenter.
The next figure will show P as the circumcenter.
The pedal triangle is fairly simple to create using the gss scripts from assignment 5 in conjuction with the gss script for the pedal triangle developed for this assignment. More diagrams will be created as time permits. I probably need to redo the first picture but time is short. The most important aspect, to me, is that I can move from page to page and use elements of two assignments to complete the assignment.
