[. . . ] The examples use two points to define translation distance and direction. 3. From the Transformation menu, select the Translate tool Press b A 3. . 4. Select: the vector or click on the page to define the translation direction and distance the translation object. The translated object displays. Exploring rotation 1. Create a point about which the object will be rotated. 142 Using Graphs & Geometry 3. Create three points whose angle defines the angle of rotation, or using the Text tool Press b 1 5. , type a numeric angle value. 4. Press to anchor the value on the work area. Triangle ready for rotation. The three angle of rotation points appear above the triangle. 5. From the Transformation menu, select the Rotation tool Press b A 4. . 6. Move to the work area and select a) b) c) the point about which the object will be rotated, and the object to rotate, and the three points that define the angle of rotation or the numeric angle value. The object is recreated in the rotated position as defined by the rotation point and angle of rotation. Exploring dilation 1. or measure an existing Press b 1 5 and press to anchor the value on the work area. Note: If you type a large number, the dilated object will not display on the work area without panning. Polygon, dilation point, and measurement on page. 4. From the Transformation menu, select the Dilation tool Press b A 5. . 5. Select the value measured or created, the dilation point, and then move toward the object. The dilation appears on the work area. 144 Using Graphs & Geometry In the following example, the polygon from the previous example was retained, but a negative number was entered using the Text tool . Press b 1 5. Other investigations You can investigate graphs by Bisecting segments Bisecting angles Finding the Locus Bisecting a segment defined on a line 1. The segment is now defined, and the perpendicular bisector is drawn. Using Graphs & Geometry 145 Creating the second point on a line. Perpendicular bisector anchored on segment between two defined points. Bisecting a segment 1. Note: A segment can be one side of a triangle, rectangle, or a polygon. 146 Using Graphs & Geometry Bisecting an existing segment (bisector not anchored on page). Bisecting the side of a polygon (bisector not anchored on page. ) Bisecting an implied segment 1. As you move away from this point, a segment and the bisector appear. Using Graphs & Geometry 147 3. Click a second time to define the other end of the implied segment and anchor the segment and bisector. Bisecting an angle 1. From the Construction menu, select the Angle Bisector tool Press b 9 4. If a triangle or other angle already exists on the work area, click once on one side of the desired angle. . 148 Using Graphs & Geometry Creating the angle bisector at the vertex of a triangle. Anchoring the angle bisector on the page. Bisecting an implied angle 1. From the Construction menu, select the Angle Bisector tool Press b 9 4. If no angle is present on the work area, you can create one by selecting three different points. The bisector line appears and is anchored on the work area when you select the third point. . Using Graphs & Geometry 149 Creating an angle bisector by defining three points. The second point represents the vertex of the angle. Angle bisector created by defining three points on the page. Note: If you select the Pointer tool and move one point of the created angle, the angle bisector moves so that it always bisects the angle. Press b 1 1. Creating a locus The Locus tool enables you to explore the range of motion of one object with respect to another object as constrained by a shared point. Create a point on the segment, line or circle. Point defined on the line segment. 3. Create another object that uses the defined point created in the previous step. 150 Using Graphs & Geometry Circle created to use the defined point on the segment. 4. From the Construction menu, select the Locus tool Press b 9 6. . 5. The continuous locus picture is displayed. 7. Move the point on the first construction. [. . . ] Check that the sensor connectors are completely inserted into the handheld/computer. This should restart the communication link. Low batteries This message displays when the batteries in your Vernier Go!Motion or CBR2TM unit are low. Note: If you connect these sensors to your computer, batteries are not required. The sensors will obtain their power from the computer by way of the USB port. [. . . ]
