Product means Software and Documentation.Documentation means the printed or electronic reference materials and other printed or electronic materials accompanying the Software.Software means The Geometer’s Sketchpad Version 5 computer program that you received from any source.Key means Key Curriculum Press, Inc., 1150 65th Street, Emeryville, CA 94608, USA.You can now construct rays or segments connecting A, B, and B' to incorporate the fixed angle into your sketch.


Dragging point A will relocate the segment (and the circle) while preserving its orientation dragging the other endpoint will reorient the segment (without changing its location). This segment will always be 2.5 cm in length (because it is the radius of a circle that is fixed at 2.5 cm) but can have any orientation. With the Segment tool, construct a segment radius of this circle from point A to any point on the circle other than point A'.This circle's radius is fixed at 2.5 cm, because you've fixed the distance between A and A' at 2.5 cm. With the Compass tool, construct a circle centered on point A passing through point A'.Delete the horizontal segment you just constructed.If you wish to construct a segment that is 2.5 cm long but has no restrictions on its orientation, follow these steps: Thus, in addition to fixing the length of the segment, you have fixed the orientation of the segment as well. This is because endpoint A' is the image of A translated by 2.5 cm at an angle of zero degrees, which is directly to the right. If you follow the above steps exactly, you'll notice that in addition to being 2.5 cm long, your segment is always horizontal. No matter how you drag either endpoint, the segment's length will remain 2.5 cm, because it has been constructed to always have that length. Now use the Segment tool to construct the segment between A and A'. Sketchpad constructs a new point A', which is the translated image of A by the distance that you entered (2.5 cm). In the Translate dialog box, enter the fixed length as the distance by which you wish to translate the point.

Select point A and choose Transform | Translate.For an arbitrary length, the easiest way to do this is with the Transform menu. To fix a segment's length in Sketchpad, you need to construct the segment in such a way that dragging cannot change its length. That is, dragging an endpoint again would change it from its current length to some other length. While you could create a segment with the Segment tool, measure its length, and drag one endpoint until its length is 2.5 cm, this segment would not be constructed to be exactly 2.5 cm long. Occasionally, you may wish to create a segment of fixed length (for instance, a segment that is exactly 2.5 cm in length). FAQ: Fixed Distance How do I construct a segment of fixed length (e.g., 2.5 cm)?
