Changing Postulates Can Provide Variety and Meaningful Learning.
Mahaffy, Donald
Mathematics Teacher, v75 n8 p677-79 Nov 1982
An approach is presented that is based on modifying the standard axiomatic system found in high school geometry books. Such changes start with the introduction of a side-angle-side (SAS) postulate for similar triangles. It is shown how the new system can prove existence and uniqueness of parallel lines. (MP)
