Sister Joseph Marie was not particularly well liked, at least not by most students in class, but there were a few students who admired her skills with geometric puzzles, and it was Amy who appreciated them the most. “I understand her crabbiness” Amy told her friends, “and I know she never smiles, but I believe she is a good person.” Amy thought that Sister Joseph always looked worried.
The stark halls of Saint Claire for Girls smelled of books and pencils, rulers and protractor, especially when you walked into Sister Joseph’s geometry class. The sister had a favorite phase she would say after describing a geometry problem. She would look up and say, “It’s all geometric.” One day the students entered the class to find a substitute teacher, Sister Marie.
“I am curious about Sister Joseph?” said Amy, as she approached Sister Marie. “Well, Amy, Sister has taken ill, and she is in a hospital in another state. I am your new teacher. Amy politely said thanks, said a prayer, and walked home.
It wasn’t until a year after graduation that Amy and three of her friends, Christine, Joyce, and Vivian each received mysterious unsigned letters with no return addresses. Their class reunion was a week away, but who wrote the letters? Amy opened her letter and it contained a geometric pattern with some writing.
Like patterns in a quilt you will find symmetry and congruence,
You will find what needs found,.
It’s all geometric.
The girls decided to take a walk to the library to search for ideas and investigate the design. The word north was written on two of them and west on the other two. Amy thought they were directional and she tried to remember where she had seen the design. Then Amy said “It is North by North west” “Like the old Alfred Hitchcock movie. We must travel northwest.”
