Let ABCDV be a rectangle based-pyramid, where V is its apex and K, M are the midpoints of its edges AD, BV respectively. What is the cross-section of the pyramid if we slice it with a plane KCM?
a quadrilateral KCMP with point P lying on the edge AV
a triangle KCM
a quadrilateral KCMP with point P lying on the edge DV
a quadrilateral KCMP with point P lying on the median KV if the triangle ADV
