What solid has a triangular cross section when the cross section is taken perpendicular to the base?

A solid with a triangular cross section when the cross section is taken parallel to the base could be either a triangular prism, a triangular pyramid, or a triangular frustrum.. I've been sitting here trying to convince myself (without actually bearing down and trying to prove it mathematically) that any cross section of a regular tetrahedron (a special case of triangular pyramid) taken perpendicularly to the base is a triangle, and I THINK this is the case, but as I said I certainly haven't rigorously proven it; I'm just unable to come up with any obvious situation where this is not true.

What is the intersection of a plane and a solid?
It is a cross section.
How can you the volume of a rectangular solid?

Which solid has a cross section with a maximum of 5 sides?
square pyramid
What solid has 7 faces 10 vertices and 15 edges?
A prism that has pentagonal cross-section
What solid figure has 3 rectangular faces and 2 triangular faces?
A triangular prism.
What three solid figures have a triangle as a cross section?
Pyramid, triangular prism, cone.
What area is formed by a plane cutting through a solid perpendicular to its axis?
A cross section is formed.
What solid figure has the same cross section when its sliced by a plane parallel to its base as when it is sliced by a plane perpendicular to its base?
Sphere
What is the intersection of a plane and a solid?
It is a cross section.
What is a circle called in a solid?
A circle in a solid is called a cross-section.
What does cross-section mean?
When a 3-dimensional (solid) object is cut by a plane, the 2-dimensional shape made where the solid object and the plane meet is the cross section.
What is the definition of a uniform cross-section?
A Uniform Cross Section is the cross section of the solid, parallel to base, such that the resulting figure has the same shape and size as that of the base of the figure.More about Uniform Cross SectionSolids like pyramids and cones have slant heights and hence do not have uniform cross section.Examples of Uniform Cross SectionThe uniform cross section of the given prism is a square.The uniform cross section of the given cylinder is a circle.In short to say, uniform cross-section are when you dissect a 3D solid and you get all same shape (uniform).
What do you notice about the cross section of a solid sphere?
Every section of a solid sphere is a filled-in circle, i.e. a disk with zero thickness.
How can you the volume of a rectangular solid?
Volume = cross-section area*length
Which solid has a cross section with a maximum of 5 sides?
square pyramid
What is the intersection of a solid and a plane parallel to the base or bases of the solid?
It is a horizontal cross-section. Its shape will depend on the shape of the solid and its orientation.
The figure formed by the intersection of a solid with a plane parallel to the base of the solid is congruent to the base if the solid is a?
The answer would be a right cylinder. A right cylinder is a cylinder that has a closed circular surface having two parallel bases on both the ends and whose elements are perpendicular to its base.
