What is a polyhedron with equilateral triangle faces?
It_is_a_triangular_prism.">It_is_a_triangular_prism.">It is a triangular prism.* * * * *While a triangular prism can have equilateral triangle faces, it has more faces that are quadrilateral (or rectangular).A polyhedron with only equilateral triangular faces could be a tetrahedron, an octahedron in the form of a square based dipyramid, or an icosahedron.
Is an icosahedron a semi-regular or regular polygon?
An icosahedron is in fact not a polygon at all, but a polyhedron. As a polyhedron it is regular however. The regular icosahedron is one of only five possible regular polyhedra. It has 20 faces, each of which is an equilateral triangle.
Does a triangle have faces?
No. A triangle is a two-dimensional polygon (flat figure). It has sides that consist of three line segments, with an interior area. Only a three-dimensional form (polyhedron) can have faces. Triangles serve as faces for any number of polyhedrons, such as pyramids.
Are all parrellelograms rectangles?
No. Only some parallelograms are rectangles. But all rectangles are parallelograms.
What is the highest vertex of a polyhedron?
It may be called an apex, but that is really only appropriate for a simple convex polyhedron.
What shapes that have 3 corners?
A triangle is the only polygon with 3 corners (vertices). There is no polyhedron with 3 corners.

Are edges only in polygons and polyhedron?
no
Are all parrellelograms rectangles?
No. Only some parallelograms are rectangles. But all rectangles are parallelograms.
All rectangles are rhombus?
No. Only some rectangles are - when they are squares.
Does a triangle have faces?
No. A triangle is a two-dimensional polygon (flat figure). It has sides that consist of three line segments, with an interior area. Only a three-dimensional form (polyhedron) can have faces. Triangles serve as faces for any number of polyhedrons, such as pyramids.
What are rigid rectilinear figures?
The only rectilinear figure is a triangle, or one composed of several triangles joined together.
Why are some rectangles squares?
All squares are rectangles also, but not all rectangles are squares, only equilateral rectangles are considered square.
What is a polyhedron that contains 0 bases?
A polyhedron has only polygonal faces and any one of them can be considered a base. Therefore a polyhedron with 0 bases cannot exist.
What is the highest vertex of a polyhedron?
It may be called an apex, but that is really only appropriate for a simple convex polyhedron.
What is non-polyhedron?
A polyhedron has "many sides" (by definiton). The only 3-D shape which does not have "many sides" is a sphere (which technically only have one "side").
