Select all the points, right-click and choose Group to Shape. Rotation We are now going to rotate the shape 90° clockwise about (0, 0). a point at (0, 0). Use the Scribble Tool to predict where the points A, B, C and D will be after they are rotated 90° clockwise about (0, 0). Select the shape and the point, right-click and choose Rotation. Use the Scribble Tool to predict where the points A, B, C and D would be if the rotation was increased to 180° clockwise about (0, 0). Select the rotated shape and click Animate Object. Use the right arrow to increase the rotation to 180°. Double-click on the rotated shape and untick Show Construction Lines. Go to Edit > Select All Scribbles and Delete. Enlargement We are now going to enlarge the rotated shape by a factor of 2 with the centre of enlargement at (0, −5). Place a point at (0, −5). Use the Scribble Tool to predict where the points A, B, C and D will be after the shape is enlarged by a factor of 2 with the centre of enlargement at (0, −5). Select the rotated shape and the centre of enlargement, right-click and choose Enlargement. Use the Scribble Tool to predict the points A, B, C and D would be if the enlargement factor was increased to 3. Select the enlarged shape and click Animate Object. Use the right arrow to increase the enlargement factor to 3. What will happen when the enlargement factor is less than 1? What will happen when it is 0? What will happen when it is negative? Double-click on the enlarged shape and untick Show Construction Lines.
