1. A parabola; it is a U-shaped graph. In the picture, it opens upwards. The conic section cuts through the bottom/base of the cone and the side at an angle.
2. A circle; it is round and it’s equation uses the radius. The conic is basically parallel with the circular bottom of the cone.
3. An ellipse; it appears as a circular/oval shape. It is intersecting the cone at an angle.
4. A hyperbola; it is symmetrical and intersects both cones.
