Students identify and determine angle pair relationships when two parallel lines are intersected by a transversal. They review the concepts of angles by watching streaming video clips online, read definitions of lines and angles from index cards, and match vocabulary with their definitions. They use the SMART board to demonstrate the content. Full Review »

Students determine the relationship between corresponding angles, alternate ulterior angles, and same-side interior angles using Geometer's Sketchpad. They determine properties of parallel lines cut by a transversal, and observe examples of finding missing measurements of angles on the board. Full Review »

Students use Geometer's Sketchpad, or other similar software. They use the equation f(x)=4x-3 to create a graph. They select two points on the line. Students count the rise/run change from two points on the line. They define rise/run as slope. Students construct parallel lines with one intersecting line through them. They explore pairs of angles.

Students explore the relationships between angles formed by two lines cut by a transversal when lines are and are not parallel. They define key vocabulary terms, then using a camera take pictures at their school of parallel lines with transverals. Students color code the sets of pictures taken by their classmates.
