Triangle Fundamentals. Lesson 3-1. B. C. A. Naming Triangles. Triangles are named by using its vertices. For example, we can call the following triangle:. ∆ABC. ∆ACB. ∆BAC. ∆BCA. ∆CAB. ∆CBA. Opposite Sides and Angles. Opposite Sides:. Side opposite to  A :.

Angles and Parallel Lines. Lesson 2-4. Transversal. Definition: A line that intersects two or more lines in a plane at different points is called a transversal. When a transversal t intersects line n and m , eight angles of the following types are formed: Exterior angles

Lesson 7. Quadrilaterals and Other Polygons. Quadrilaterals. A quadrilateral is a four-sided figure like the one shown. The sides are line segments connected together at their endpoints, called the vertices (plural of vertex ) of the quadrilateral.

Folding Polygons From a Circle. A circle cut from a regular sheet of typing paper is a marvelous manipulative for the mathematics classroom. Instead of placing an emphasis on manipulating expressions and practicing algorithms, it provides a hands-on approach fro the visual and tactile learner. .

Parallel Lines and Transversals . Honors Geometry Chapter 3, Section 1. Notes . What does it mean for two lines to be parallel? Parallel lines: Lines that do not intersect and are coplanar . What about lines that don’t intersect and aren’t coplanar?
