Whathappens if you move D? E? F? Move line EG up or down. Make sure the interior of your shape is highlighted and thengo to the ‘measure’ menu and choose ‘area’.

Let’suse GSP to measure the area of your quadrilateral.

Yourconstruction should now look like this: You can change the color by going to the ‘display’ menu andchoose a different color. To dothis, use the point tool to highlight all four points and then use the‘construct’ menu and choose ‘Quadrilateral Interior’.

What’sthe name of this shape? Let’sconstruct the interior.

Then highlight line FG outside thesegment and hide the line. Choose points F and G, construct a segment.

Nowwe need to cut this line down to a segment.

Label the intersection of this new lineand the upper line G. Construct a parallel line that passes through point F.

Constructanother point on the lower line and label it F.

Constructa segment, label it DE, that goes from the lower lineto the upper line.

This new line will pass through point Cand be parallel to your original line.

Highlightboth point C and line AB and construct a parallel line.

Constructpoint C somewhere above the line.

Opena new sketch and construct a horizontal line AB.

Now, let’s take what we’ve learned about constructions anddo some investigations with area.

Constructthe segment FK and hide the line FK.

Label the intersection of line CD andthe perpendicular F.

Constructa line that is perpendicular to CD that also passes through point K.

Constructa line that is parallel to CD and passes through point K.

To begin,we need to become familiar with some of the commands in GSP. The firstthing you need to do is open the program. The wrap-up lessons are ideal for reviewing.Todaywe’re going to use a program called Geometer’s Sketchpad (GSP) to do someactivities in geometry.

The software files accompany the activities and projects. Some projects are suited for independent review, whereas others are more suited for smallgroup work. Projects are also included, which give students additional review of the concepts addressed in the activity lessons. Answers are also supplied for many of the students' lessons and the wrap-up review activities.

The teacher's notes gave guidance on how to present lessons, listed the concepts and prerequisites that should be stressed, identified vocabulary related to the lesson, and included instructions for teacher demonstrations.

The tours and quick reference guides were very effective in helping us become comfortable with the commands for The Geometer's Sketchpad. Neither my students nor I had experience with this software before using it and the activities that came with the text. Additionally, each lesson comes with a quick reference guide that provides additional instruction relating Sketchpad to the lesson. The first unit consists of tours to introduce teachers and students to the skills needed for Sketchpad's use. The software provides interactive activities and teacher demonstrations that accompany the text. The disks operate in conjunction with The Geometer's Sketchpad software.

Two software disks contain the text for Microsoft Windows and for the Macintosh. These divisions compose the book: Unit 1-Tours Unit 2-Points, Lines and Angles Unit 3-Triangles Unit 4-Quadrilaterals Unit 5-Symmetry Unit 6-Transformations and Unit 7-Constructions. Each unit contains teacher instructional notes, activities, projects, wrap-up lessons, and quick reference guides. This book contains interactive lessons that develop higher-level-thinking skills in middle school geometry.
