Question 1 Select Cone in the list of shapes. Vary the angle between the intersecting plane and the vertical axis, and identify the shapes of
the cross sections formed. Try to form as many different cross-sectional shapes as possible. You might find it helpful to start
with a horizontal intersecting plane and gradually increase the angle of the plane until it is vertical. Be sure to observe the effect
of moving the plane without rotating it.
