Shape with four faces?
A three-dimensional figure or shape, such as a tetrahedron, has four faces. These faces are equilateral triangles. A tetrahedron also has four vertices and 6 edges.
What is a quadrahedral?
Quadrahedral is not a word. A tetrahedron (tetra- is the Greek prefix for four, as opposed to quadra-, which is Latin for four) is a four-sided solid figure, basically a pyramid formed from four equilateral triangles.
How do you make a concave hexagon from 4 triangles?
Put four equilateral triangles so that each one of them has a vertex at a single point and the triangles abut one another. The shape will be 4/6 (= 2/3) of a regular hexagon.
What is a tetrahedron shape?
A pyramid with a triangle as base is considered as a tetrahedron. It is a three dimensional polyhedron with 4 equilateral triangles as its sides. If one would look at the word tetrahedron, it literally means "with four planes".
What is a solid with only 4 triangles?
A Tetrahedron has four triangular sides.
Which Platonic solid has four faces that are equilateral triangles?
tetrahedron
What shape can you make using four equilateral triangles?
A parallelogram.
What 3d shape has 4 congruent triangles?
A tetrahedron has four equilateral triangles as sides
Shape with four faces?

Does a tetrahedron have any right angles?
No. A right angle would be 90 degrees; a tetrahedron is composed of four equilateral triangles, which by definition have equal angles of 60 degrees apiece.* * * * *Wrong!A tetrahedron is a solid shape enclosed by any four triangles. Only a regular tetrahedron that requires equilateral triangles. So an ordinary tetrahedron can have right angles - up to 3 of them at one vertex.
What is the shape that has four congruent equilateral triangles?
The regular tetrahedron - one of the 5 platonic solids.
Which solid figure has 4 tringluar faces?
A triangular-based pyramid - it consists of four equilateral triangles, joined at the points.
What shape has 4 faces which are congrugent triangles?
A four faced figure is a tetrahedron. If they are all congruent triangles, they are all equilateral triangles and it is a regular tetrahedron - one of the 5 Platonic Solids.
What is an octahendron?
Well a Regular Octahendron is simply a platonic solid composed of 8 equilateral triangles, four of which meet at each vertex.
What kind of four sided figure is made using two equilateral triangles?
Rohmbus is a four sided figure (quadrilateral) that is made up of two equilateral triangles
What is a quadrahedral?

What are the special features of a square based pyramid?
It has a four sided square base and four other triangular sides reaching up to an apex. It is a pentahedron. If the four triangles are equilateral, it is known as a Johnson solid, and six of the pyramids will fit together to make an exact cube. If the four triangles are not equilateral, then they are isosceles.
