Using The Geometers Sketchpad by Reynolds and Fenton (2006) and the goal is to lead. Are your observations still the same?ġ8.) Based on your observations, make a conjecture about the relationship of triangle ABC and its midline DE. evidence that the student had competent, error-free knowledge with. To do this, type
Version 4.07 is a free update for all version 4 users. The last minor update to version 4 was 4.07, and version 4 users are encouraged to use that version until they can upgrade to version 5. First we will display the measure of angle ABC. The Geometer's Sketchpad Version 4 was first released in December 2001, and has been replaced by Version 5, described above. Is your observation still the same?ġ4.) Next, we will try to observe the relationship among the interior angles of two triangles – triangle ABC and triangle ADE.
What can you observe about the lengths of segments BC and DE?ġ3.) Select the drag vertices option button on the toolbar and drag the vertices of the triangle. 12.) Next type BC in the text box and then press the ENTER key.
