Sections of:
cones, spheres, ellipsoids, tori, paraboloids, hyperboloids.
In fact, consider the graph of any function in 2-dimensions that is always non-negative. Rotate the curve around the x-axis to generate a 3-d shape. A straight line will generate a cone, a square root function will generate a paraboloid, a semicircle will generate a sphere and so on. A wobbly line will generate a lumpy 3-d shape [NB: wobbly and lumpy are very technical terms ;) ]
A plane at right angles to the x-axis will intersect all these curves in a circle.

3 dimensional figures with triangular sides? Prisms and Pyramids 2 dimensional figures that can be divided into traingles? Any n-gon with n > 3 can be divided into n-2 triangles.
geometric solid
Traditional geometric figures have dimensions which are integers: 0 for a point, 1 for a line or Mobius strip, 2 for a plane figure or Klein bottle, and 3 for a solid. Fractals have dimensions which are not integers.
They exist in the realm of typographic errors. Triangular prisms and rectangular prisms are solid geometric figures.
It is a 3 dimensional shape and in geometrical terms it's only limited to one of 5 perfect solids
Circles and rectangles are plane (2-dimensional) figures, so it doesn't seem that they can be used to construct solids.
A solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.
A prism.
Yes it is. Anything that is 3D is usually a geometric solid. (Think)
A sphere is a geometric solid because it has 3 dimentions.
2 consecutive circles ============= As a solid geometric figure, a doughnut shape is called a torus.
