Question

Which best describes the two-dimensional shape created by the cross-section shown? *



Circle

Ellipse

Triangle

Rectangle​

Answer 1

Answer:

when we half the cone is the result is Triangle

Answer 2

The option that correctly describes the cross-sectional shape formed here in the figure is option 3rd: Triangle.

• The three-dimensional solid shapes are the result of two-dimensional shapes that are generated in three planes or three axes.
• The geometrical shape or figure from which the particular solid shape is formed can be recognized by its creating its cross-section. However, cross-sections can be created in different directions, and based on this different two-dimensional shapes are obtained.
• The given figure shows the solid three-dimensional cone which has a circular base and its tapers at the vertex.
• The figure is cross-sectioned from its vertex. The face of the cross-section formed is best described by a triangle.
• The circle is obtained when the sphere is cross-sectioned. Also, an ellipse is obtained from a sphere or cone that is cross-sectioned in the cross direction.
• A rectangle is the two-dimensional shape obtained when a cuboid is cross-sectioned.
• Hence, triangle is correct answer for the question.
