Teachers' Domain, Lines, Angles, and Triangles: Lesson 1 - Introducing Lines and Angles, published April 18, 2011, retrieved on ,
Introducing Lines and Angles is the first of eight self-paced lessons in the “Lines, Angles, and Triangles” section of KET’s GED® Geometry Professional Development Online Course. This lesson introduces lines and angles, including how to name angles and recognize degrees. It also extends the discussion of lines to two important pairs of lines that are featured in later lessons⎯parallel lines and perpendicular lines.
The GED Geometry Professional Development Online Course is designed to help you review and build your skills and knowledge of geometry concepts and to help you to gain confidence in preparing your learners for a substantial portion of the GED Mathematics Test.

Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
