The development of this page parallels the teaching of the SYMMETRIES course (MAT 103) at SUNY Oswego during the Fall 2001 semester, as shaped after Margaret Groman's introduction of MAT 103 in 1992 and my own ten consecutive semesters of MAT 103 teaching prior to a 2000-2001 sabbatical leave (during which the MAT 103 textbook was essentially completed). The labs posted in this page are not copyrighted and may be freely reproduced and used at will, mentioning their origin if appropriate. The numbers in brackets represent the sections from Isometrica related to each lab.
