Question

Which term best describes the horizontal cross-sections of an oblique cone?

O A. Congruent discs
OB. Similar discs
OC. Similar polygons
O D. Congruent polygons

Answer 1

B. Similar discs

Explanation:

Definitions

Cone: A three-dimensional solid figure that has a circle at one end (the "base"), a point at the other end (the
`\sf a\:\!pex`), and a curved side.

Right Cone: A cone where the
`\sf a\:\!pex` is aligned on the center of the base.

Oblique Cone: A cone where the
`\sf a\:\!pex` is not centered over the base.

Horizontal Cross-section: The intersecting plane parallel to the base of the solid figure.

Congruent: The same shape and size.

Similar: When one shape can become the other after being resized, reflected, translated or rotated.

Disc: The region in a plane bounded by a circle.

Polygon: A two-dimensional closed shape with a minimum of 3 straight sides.

Therefore, the horizontal cross-sections of an oblique cone are similar discs.
