The topics to be studied include : basic geometric figures, deductive reasoning and proofs, postulates and theorems for parallel lines and planes, corollaries and theorems for congruent triangles, properties and theorems for quadrilaterals, inequalities of triangles, and polygons. A specific geometry textbook is required for the course. It is used in many high schools in the US. See my TEXTBOOK web page for complete info.
The course may be began at any time and is selfpaced. Each day that an assignment or test is submitted by the student he will receive his grade and corrections and comments within a few hours by email. The instructor, Susan Johnsey, is available daily for questions and to grade your work. I answer email at least 350 days of the year.Be sure the student has a valid email address and that he can easily check his emails and SAVE them in a folder on his computer.

Geometry Class for High School (second semester) is a continuation of my first semester geometry course. This course will present a good knowledge of Geometry which includes, but is not limited to: 1. proving theorems, 2. finding the angles, number of sides, perimeter, and area of polygons, 3. calculating the surface areas and volumes of polyhedrons, cylinders, spheres, cones and pyramids, 4. solving for the angles and sides of right triangles using Pythagorean theorem and trigonometric ratios , 5. finding the various measurements of circles and segments of a circle (arcs, sectors, chords, secants, tangents, central angles and inscribed angles) 6. understanding the use of algebra in analytical geometry, (linear equations in two variables, slope, midpoint, distance formula, equation of circles, reflections, rotations, and translations). 7. drawing translations and reflections of graphs In the United States most State Boards of Education require completion of the first and second semesters of Geometry for graduation from a public or private high school. There is a required book for the course. See TEXTBOOK web page for complete info for purchasing the book.
