A polyhedron made from four triangles that are not equal is called a tetrahedron. Specifically, if the triangles are not congruent, it is referred to as an irregular tetrahedron. Tetrahedra are three-dimensional shapes with four triangular faces, six edges, and four vertices.
What else can I help you with?
What is a solid shape made out of eight equilateral triangles?
A solid shape made out of eight equilateral triangles is called a triangular bipyramid. This polyhedron consists of two triangular pyramids (tetrahedra) joined at their bases, creating a three-dimensional figure with eight triangular faces, six edges, and four vertices. The symmetry and uniformity of the equilateral triangles give it a distinct geometric shape.
What is a polyhedron?
A polyhedron is a three dimensional figure made up of sides called faces, where each face is a polygon.
Why is a rectangle polyhedron not regular polyhedron?
The sides of a rectangle are not all equal so a rectangle is not a regular polygon. And, as a consequence, any 3-dimensional shape made from rectangles cannot be a regular polyhedron.
What shape has 5 faces made up of triangles and rectangles?
The shape is a triangular prism. This is a 3-dimensional polygon with two ends that are triangles and three rectangular sides connecting them.* * * * *FYI, a 3-dimensional polygon is known as a polyhedron.
What is a solid that is bounded by polygons which are called faces?
It's a polyhedron. A polyhedron (plural: polyhedra) is a three - dimensional figure made up of sides called faces, each face being a polygon.
What do you call a pyramid with a square base?
Square Based PyramidTetrahedron: A tetrahedron is a polyhedron made of 4 triangles. A "regular tetrahedron" is a tetrahedron where the triangles are equilateral. (A polyhedron is any 3 dimentional figure made of flat surfaces and straight lines.)
What polyhedron's net is made of four triangles and one square?
A square based pyramid.

What is a shape made from pentagons and triangles?
A shape made from pentagons and triangles can be classified as a polyhedron, specifically a type of Archimedean solid known as a truncated tetrahedron or a snub dodecahedron, depending on how the shapes are arranged. In these solids, the pentagons and triangles combine to create a three-dimensional structure with distinct faces. The arrangement of these polygons gives the shape unique geometric properties and symmetry.
Is a square made up of 4 equilateral triangles?
No, a square is not made up of four equilateral triangles. A square has four equal sides and four right angles, while equilateral triangles have three equal sides and three equal angles, each measuring 60 degrees. However, you can arrange two equilateral triangles to form a rhombus, which can be manipulated to fit within a square, but they do not constitute the same geometric shape.
How many hexagons made into a hexahedrons?
http://en.wikipedia.org/wiki/Hexahedron Generally, a hexahedron is any polyhedron with six faces, most commonly a cube. No hexahedron has a hexagon for any of its faces; most have squares or triangles.
What figure is made of triangles quadrilaterals and other two dimensional figures?
They are called polygons
