The double cone is intersected by a vertical plane passing through the point where the tips of the cones meet. What is the shape of the cross section formed?

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
