1. Drag point A with the mouse along the outline of the flower. What do you notice? Write down your observations. 

2. How many axes of symmetry does this flower have? 

Hint: Drag the green points in order to change the position of the line of reflection. Then, repeat step (1) for every position of the line. 
Hint: Click the little icon in the upper right corner in order to delete the traces.

3. Make a sketch of this worksheet including the flower and all lines of symmetry you were able to find.
