This site from the University of North Caroline at Wilmington provides great information on the lines in a plane. The information that is given is in-depth and complete, touching on the slope of a line, equations of lines, and linear...

Provides examples and a video lesson that illustrates parallel and perpendicular lines.

Characteristics of a line are explained to young scholars through four different lessons. Topics include intercepts, slope, and special line cases. The lessons have an overview, materials, procedures, and evaluation techniques.

In this task, students are shown three unit squares and two line segments connecting two pairs of vertices. They are asked to find the area of a triangle formed by intersecting lines. They can solve it using coordinate geometry or...

Learn all about the basic geometric constructions in this test prep lesson. You will explore line segments and points, and understand key terms like the terms parallel and perpendicular. Construction activities and interactive online...
