The topic has occurred on the forums before; but maybe someone has fresh ideas. How do we justify the need for high school Geometry for high school students who are headed for college and science or engineering careers? When such students want to earn a degree in some physical science or engineering, "remedial" Geometry is not part of the curriculum; for most purposes, students may skip this Geometry course and not notice much difference. The degree does not call for it. Students can do their Trig>PreCalc>Calc1,Calc2,Calc3>Differential Equations... Omitting "Geometry" does not hurt anything. Intermediate Algebra did not really require it; Trigonometry did not really require it. Geometry at the high school level is a "Foundation Level Course". Nice classification, but still not really essential for Algebra 2; and any Geometry needed in Trigonometry is usually well enough taught IN Trigonometry. I have found one important possible reason justifying at least one feature in Geometry - that being the Triangle Inequality Theorem. People, help me clarify and identify other reasons which we can use to justify studying Geometry to high school students and to other "remedial" level Math students in college.
