Plane Geometry is developed as a mathematical system treating points, lines, and planes as undefined terms. Deductive reasoning is introduced early in the course as the two-column deductive proof is developed. Congruent figures are treated in detail and similar polygons lead to a study of proportions. The Pythagorean Theorem and special right triangles are studied, as are properties relating to the circle. Students will find the perimeter and area of plane figures, and the surface area and volume of three-dimensional figures. Transformational geometry will also be studied.
