Using the Construct>Intersection command will give us two intersections, but we only need one.

Note that one of the intersections of the circles is our third vertex. Your sketch should look like the second figure. To do this, select point F and segment BC, and click Construct, and then click Center By Center+Radius. We construct the circle with center F and radius BC. To do this, select point D, select AB, click Construct, and then click Center By Center+Radius.Ĩ.) Next, we copy the third side BC. This means that we will create a circle with center D and radius equal to the length of AB. To do this, be sure that the circle (and no other object) is selected, click the Display menu from the menu bar, and then click Hide Circle.ħ.) We now copy AB. Move point C or A and observe how the radius of the circle adjusts.Ħ.) Next we hide the circle. This will produce a circle with center D and radius equal to the length of AC.ĥ.) Intersect the circle and the ray by selecting both objects, clicking the Construct menu and the selecting Intersection. Select point D, then select segment AC (do not select the points!), click the Construct menu, and then click Circle By Center+Radius. To do this, be sure to deselect all the objects by clicking on the vacant part of the sketch pad. Your sketch should look like the first figure.Ĥ.) Next, we will construct a segment DF which is congruent to AC.

Now, choose the Ray tool.ģ.) Click two distinct points on the sketch pad and display the names of the two points. To do this, click the Straightedge tool box and hold the mouse button to display the other tools. The Geometer's Sketchpad holds great promise as a technology that can energize the geometry curriculum however, teachers must carefully design its implementation so that students reap the greatest possible benefit from its use.2.) Next, we construct ray DE.
GEOMETER SKETCHPAD ACTIVITIES SOFTWARE
Instead of using teacher and student interviews as evidence of GSP's effectiveness, researchers should seek quantitative data that shows how specific uses of dynamic geometry software lead to greater performance on standardized tests. More research is necessary to determine how teachers can use The Geometer's Sketchpad most effectively in the classroom. In this way, students continue to receive the benefits of GSP throughout the year without becoming bored by its constant use. Teachers should ensure that each pair moves at a pace that allows both students to comprehend the material.īecause student interest waned when classes used The Geometer's Sketchpad every day for an extended period of time, I recommend using GSP as a tool to supplement more traditional lessons and hands-on activities rather than as the primary instrument of instruction. GSP also provides teachers with opportunities to have students participate in partner work. The research shows, however, that this improved engagement wanes over time therefore, teachers must be cautious not to overuse GSP. The dynamic nature of The Geometer's Sketchpad may lead students to improve their engagement with the material. While teachers must devote some time at the beginning of the year to training students to use GSP, the class will earn this time back in the long run because the dynamic aspects of the tool prevent teachers and students from having to draw a new figure by hand each time. Students in this environment feel a sense of control over their learning, even when the teacher is the person designing the sketches. With GSP, the classroom becomes a student-centered rather than teacher-centered environment. By using the tool's dragging features, students can observe countless examples of different figures quickly and easily. The Geometer's Sketchpad (GSP) takes the traditional pencil-and-paper geometry class and transforms it into a dynamic learning environment.
