A TRANSFORMATION APPROACH TO TENTH-GRADE GEOMETRY

A TRANSFORMATION APPROACH TO TENTH-GRADE GEOMETRY

There are many individuals who have called for the insertion of transformations into the tenth-grade geometry course; for example, Jeger (1966, preface), Adler (1968, p. 226), and Betz (1933, p. 110). For some time, texts have been appearing with a section or chapter devoted to reflections, rotation...

Zusammenfassung:There are many individuals who have called for the insertion of transformations into the tenth-grade geometry course; for example, Jeger (1966, preface), Adler (1968, p. 226), and Betz (1933, p. 110). For some time, texts have been appearing with a section or chapter devoted to reflections, rotations, or other kinds of transformation (Kelly and Ladd 1965; Fischer and Hayden 1965; Fehr and Carnahan 1961; and Jurgensen; Donnelly; and Dolciani 1969).
