[. . . ] Cabri and Cabri Geometry are trademarks of CabriLog. TI-84 Plus Cabri Jr. Construct perpendicular and parallel lines; perpendicular and angle bisectors; and geometric loci. Transform objects through translation, reflection, rotation, and dilation. Compute lengths, areas, perimeters, and angle values of relevant objects. [. . . ] The perpendicular bisector is drawn. After you select the first point, a dotted line is drawn. After you select the second point, it becomes a solid line. TI-84 Plus Cabri Jr. Move the pointer to each of the three points that create the angle, pressing at each point. The second point you select is taken as the vertex of the angle. Drawing a Midpoint To draw the midpoint of two points or the midpoint of a line segment: 1. Select two points by moving the pointer to each of the points, pressing at each one. After you select the second point, the midpoint is drawn. TI-84 Plus Cabri Jr. Application Page 28 Drawing a Circle Using the Compass Tool When you draw a circle using the compass tool, a line segment or the distance between two points is the radius for the circle. Move the pointer to the first point and press , then move the cursor to the second point and press . To clear the entire screen, open the F5 menu, select Clear, and then select All or press ?To clear an object, open the F5 menu, select Clear, select Object, move the pointer to the object, and then press . TI-84 Plus Cabri Jr. Application Page 29 Using the Undo Feature Open the F1 menu and then select Undo to undo the last action. Draw the perpendicular bisector of Point F and another point taken on AB, named M. The shape of the pointer changes to a double arrow. TI-84 Plus Cabri Jr. Draw a line or line segment around which the object will be reflected. Draw a line segment or two points that define the length and direction of translation. Select either the line segment or the two points, and then select the object. A new translated object is created. Tip After you have defined the length and direction of the translation, a point is drawn that shows where the translated object will be placed. Rotation 1. Draw a point around which the object will be rotated, and then draw three points whose angle will determine the angle of rotation. Select the point around which the object will be rotated, and then select the object to rotate. TI-84 Plus Cabri Jr. You can also select a number such as an angle measurement or a number that you have entered using the Alpha-Num tool for the angle of rotation. This number must be on the screen before you select the Rotation tool. If you use an angle measurement, the rotation will be between 0 and 180 degrees because the angle measurement tool measures the interior angle. Dilation 1. [. . . ] saving CurrCaJ2 on your computer or another unit, and making use of it later when you have enough available RAM on your device. You have selected Open from the F1 menu, but there are no saved figures on your calculator to open. You have entered a file name for your figure that already exists. Select OK to overwrite the existing file, or select No to return to the Save dialog box so that you can enter a different file name. TI-84 Plus Cabri Jr. Application Page 54 Error Message Description You cannot use or CURRCAJU or CURRCAJ2 as a file name. [. . . ]
