square
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.
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.
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.
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".
A Tetrahedron has four triangular sides.
tetrahedron
A parallelogram.
A TETRAHEDRON. Incorrectly named as a 'triangular pyramid'.
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.
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.
The regular tetrahedron - one of the 5 platonic solids.
A triangular-based pyramid - it consists of four equilateral triangles, joined at the points.
No, two equilateral triangles do not make a square. A square has four equal sides and four right angles, while an equilateral triangle has three equal sides but three angles that add up to 180 degrees. When two equilateral triangles are put together, they do not form a shape with four equal sides and four right angles, which is the defining characteristic of a square.
A tetrahedron is a polyhedron with four triangular faces, six edges, and four vertices. It is a three-dimensional shape formed by connecting four equilateral triangles at their edges, resembling a pyramid with a triangular base.
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.
Well a Regular Octahendron is simply a platonic solid composed of 8 equilateral triangles, four of which meet at each vertex.
Rohmbus is a four sided figure (quadrilateral) that is made up of two equilateral triangles
