No, a t/hedron has 4 vertices where three sides meet.
tetrahedron ( tetrahedra or tetrahedrons) is a polyhedron composed of four triangular faces, three of which meet at each corner or vertex. It has six edges and four vertices. The tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has four faces.The tetrahedron is the three-dimensional case of the more general concept of a Euclidean simplex.The tetrahedron is one kind of pyramid, which is a polyhedron with a flat polygon base and triangular faces connecting the base to a common point. In the case of a tetrahedron the base is a triangle (any of the four faces can be considered the base), so a tetrahedron is also known as a "triangular pyramid".A cation is a positively charged ion, which is an atom or molecule with one or more of its electrons removed.
There is no specific name for lines that meet at one point, but lines that meet at a point, the point is called the intersection point.
point I believe the word you're looking for is "intersection". Two non-parallel lines that lie in the same plane will have one point in common where they cross, and that point is the intersection.
One: a tetrahedron is a single solid.
A tetrahedron is a polyhedron with four sides (tetra means 4) that are triangles. So one fourth of a tetrahedron is a triangle.
Two lines that meet at one point is called an intersection. More than two seperae lines can be intersected at one point.
Correct. Two lines never meet in more than one point.
The ratios are "small to large".
Lines intersect if the meet at one point. Perpendicular lines also meet at one point, but their intersection is a right angle. Intersecting lines in the plane do not meet at two points.
No. Whereas a tetrahedron has four triangular faces, at any point in time only one of them may be called a base.
To make a tetrahedral shape, start with a triangular base and then connect three more triangles to the sides of the base, making sure all the triangles meet at a single point. This will create a 3D shape with four triangular faces, known as a tetrahedron.
One line cannot be coplanar, and there is nothing for it to meet.
