Every possible cross section of a three-dimensional figure is a circle. what is the figure? cone cylinder circle sphere

The answer is sphere on e2020. Hope this helps. : )

" Any cross-section of a sphere is a circle(All circles are similar to one another)".

Step-by-step explanation:

" In geometry and science, a cross-section is a non-empty intersection of a solid body in three-dimensional space with a plane" .

cone:

the horizontal cross-section of a cone is circle, while its vertical cross-section is a triangle.

Cylinder:

the vertical cross-section of a cylinder is rectangle, while it's horizontal cross-section is a circle.

Circle:

It is a two dimensional figure. so cross-section is not possible.

sphere:

Any cross-section of a sphere is a circle.

Hence answer is sphere.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
