M 333 L Fall 2010 Lab Assignment #1 Part I: Geometer’s Sketchpad Tours Refer to the sections of "Geometer's Sketchpad (Version 4) Learning Guide" which are posted online in the Handouts folder "Geometer's Sketchpad Learning Guide (Excerpts)". If you purchased Sketchpad, it came with your software so you have it already : Read pages 9-14 Perform Tour #1 (pp. 16-20) At the end of Step 15, print out the state of the sketch at that time and hand it in as page 1 of the solutions. Place in a caption the following information: . Name, Lab #1, Tour #1, Step 15. At the end of Step 20, print out the state of the sketch at that time and hand it in as page 2 of the solutions. Place in a caption the following information: . Name, Lab #1, Tour #1, Step 20. NOTE: When printing a sketch, always select “Print Preview” first and then select “Fit to Page”. Otherwise, in some of the larger sketches, the sketch is split over several pages and is impossible to see and it wastes paper. Sometimes you need to lower the %-reduction number at the top a little more for it to reduce to a single page. Perform Tour #2 (pp. 21-24), print out the final sketch to hand in as page 3 of the solutions. Place in a caption the following information: Name, Lab #1, Tour #2 Part II: Finding the locus of points which are equidistant to two given points. 1. In a new sketch, draw line segment AB which will remain fixed. 2. Construct a point C and measure the distances CA and CB. To do this, select the two points and and within the “Measure” menu select “Distance”. 3. Move point C around until the measurements are equal, that is, until CA = CB. 4. Construct 7 more points and measure their distances to A and B respectively and position them so that each is equidistant to A and B. Position 4 points in one of the half-planes determined by line AB and position the other 4 points in the other half-plane. 5. Then, complete this conjecture and place it in a caption: "Given a segment, the line which is perpendicular to the segment and passes through the midpoint of the segment is called the perpendicular bisector of the segment. The locus of points which are equidistant to two points A and B is _____________________________________ ." 6. Print the final sketch to hand in as page 4.
