You will learn the concept of congruent angles, segments, and >triangles. You will also learn the concept of similar figures, the >Pythagorean Theorem, circles, area, surface area and volume of various >geometric figures. -Marielouise, for the T2T service Thanks for visiting our on-line community.

Please read more about this possibility: http://www.drexel.edu/ia/mathforum/. Hi, Karen, I read your question on the CPAM website and it intrigued me. I fully support Claudia's response to you about using other texts ...especially Discovering Geometry and the computer program Geometer Sketchpad. Both of these will challenge your daughter's creative instinct. Geometry is more than just what your Pennsylvania curriculum states. I have always considered it the mental structure upon which much of mathematics is built. The Geometer Sketchpad enables students to explore without the tediousness of constructions by hand. Has your daughter built three dimensional models of standard figures as well as the Platonic solids and Archimedian solids? Use straws, rubber bands or "stick-um" (used to hold candles upright in their bases) to build open models and see what happens to diagonals of the solid. Has your daughter explored origami? Has your daughter asked herself what happens to the equation of a line when it moves off the two dimensional plane and is seen in three dimentional space? What happens to the equation of the line in three space? How does the equation of a plane relate to the equation of a line? If the solution of a system of two equations in two unknowns is either void or a point in a two dimentional sysstem, what is the solution of the system of three equations in three unknowns? This is coordinate geometry in three space. This is important because once the mind abstracts and is able to see the progression from one to two to three space, then n- dimensional space is easier to comprehend. Can a geometry student do this? Yes, I have seen many do it. However, this is a situation where building models with manila board and string not only helps one see the solution of problems but also develops the "eye" for being able to draw and read three- dimensional figures. Unfortunately, for me, I have been out of the high school classroom for more than 10 years and cannot direct you to texts that can help you. Has she studied probability? Geometric probability is a good problem solving method for some problems. Hopefully this will give you the idea that there is more to geometry than is in high school textbooks. Marielouise
