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. To begin this activity, open up the files that you downloaded and follow the instructions in the Word document.Ĭopyright © 1995-2015, Pearson Education, Inc.Todaywe’re going to use a program called Geometer’s Sketchpad (GSP) to do someactivities in geometry. After you have downloaded the file below, you will need to unzip it to access the files that you need.
#Geometer sketchpad activities download
You will need to download these files to your hard disk for this exercise. This technology application consists of a Microsoft Word document and 2 files that use The Geometer's Sketchpad. If you need to refresh your memory, take a look at Exercise 7A, 'Transformations', in the Maths for Vic 8 coursebook. You can also make up a shape of your own to investigate. Translate, reflect and rotate the Geometer's Sketchpad files supplied, and complete the table.
To begin this activity, open up the files that you downloaded and click here for instructions. You will need to download the Sketchpad files to your hard disk for this exercise. This technology application consists of an instructions sheet and 5 files that use The Geometer's Sketchpad. Which patterns tessellate? Take a look at Exercise 7H, 'Exploring tessellations', in the Maths for Vic 8 coursebook, to find out more. You can choose out of a triangle, square, pentagon, hexagon and octagon. Reflect The Geometer's Sketchpad shapes supplied, to create tessellations. (NB: If you follow the link above to the Keypress website, you will download version 4.) If you do not have this program, please click here.Īll files have been supplied in both versions 3 and 4 of the program. You will need to have The Geometer's Sketchpad to complete these activities.
