[. . . ] Create a line or segment about which the object will be reflected. 140 Using Graphs & Geometry 3. From the Transformation menu, select the Reflection tool Press b A 2. . 4. 5. On the work area, select the reflection line or segment. The object reflection displays on the page. 6. To anchor the reflection, click on the page or press . Exploring translation 1. Create an object to translate (duplicate). You can define the distance and direction of translation by creating a vector, or selecting two points "on the fly". Using Graphs & Geometry 141 To use a vector, define it before performing the translation. 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 rotation point is labeled with coordinates. 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. Create an object. Using Graphs & Geometry 143 2. 3. Create a point that is the center of the dilation. Create a number using the Text tool length. 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. From the Construction menu, select the Perpendicular Bisector tool . Click on the line to select one end point for this segment. Move to another point on the line and select it. 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. From the Construction menu, select the Perpendicular Bisector tool .
