a dodecahedron
A triangle is a shape with three sides and three angles. This is a very basic shape taught to young children.
A shape with three and only three sides is a triangle, but it is not possible for a triangle to have three perpendicular sides.
Three-dimensional. It has height, width and depth.
No such shape exists.

In mathematics, they are usually refered to as Solids.
Any 2-dimensional shape can be folded to form a 3-d shape. For example, any work of origami.
Because they are dimesional figures either way!
It is a line.
It depends. Different objects require different formulas. For a basic cube, it is width times length times height
Two Dimensional means that there are two dimensions.
A globe is the most accurate representation of the Earth because it is a three-dimensional sphere that closely mirrors the actual shape of the planet. Flat maps distort the size and shape of landmasses when projecting a spherical surface onto a two-dimensional plane, resulting in inaccuracies in scale and distance.
like you can draw a three dimesional repesentation of a cube on a shhet of paper so we can "draw" a three dimesional representaion of the fourth dimension .It would be a cube inside a cube with all of the corners joined by a line from exteranl surface of the inner cube to the inner corner of the external cube. This in affect is a shadow of the fourth dimesion. See "Flatland" for explaination of how 2D would try to describe 3D..
A two-dimensional shape with three sides is a triangle. A three-dimensional shape with three faces is a cylinder.
Yes, as long as the equilateral triangles are all of the same dimensions. One can be he base while the other three will have one edge on the base and he other two connecting to another triangle with the three standing up triangles meeting at one point.
Triangle is a shape with three sides.
