A triangle. Also, any shape that has no corners, such as a circle or an ellipse.
you call a two dimensional shape with six sides a hexagon
There is none because a triangle is a 2D shape and volume measures 3D shapes ----------------------------------------------------------------- There is not one. Triangles are two dimensional, volume is three dimensional, a triangle can therefore have an area but not a volume.
When two sides (called faces) of a 3-dimensional shape meet, they meet at an edge.

No. Half is a number; triangle is a two dimensional shape.
A two-dimensional shape with three sides is a triangle. A three-dimensional shape with three faces is a cylinder.

Two-dimensional.

You don't. A triangle is a two-dimensional shape and thus has no volume. The area of a triangle is equal to 1/2 the length of the base times the height.
a triangle * * * * * Wrong on at least two counts: A triangle need not be irregular and a triangle is not a three dimensional shape. Any pyramid other than a regular triangular pyramid (tetrahedron), any prism other than a cube are some examples.
A shape that has 10 sides (two dimensional) is called a decagon. A shape that has 10 faces (three dimensional) is call a decahedron.
