Any 2-dimensional shape has a vertex where two sides meet.Any 3-dimensional shape has a vertex where three or more faces meet.
A shape that has 10 sides (two dimensional) is called a decagon. A shape that has 10 faces (three dimensional) is call a decahedron.
An octagon is two dimensional and has eight sides.
A decagon. A two-dimensional shape (plane figure, or polygon) which has ten sides is a decagon. A three-dimensional shape (polyhedron) which has ten sides (plane faces) is a decahedron.
Assuming that each vertex is used to connect exactly two sides, all two-dimensional shapes will have the same number of sides as vertices. So a shape with 4 sides will have 4 vertices and a shape with 3 sides will have 3 vertices. Think of a square (4 sides, 4 vertices) and a triangle (3 sides, 3 vertices).
That is called a polygon.
A two-dimensional shape with three sides is a triangle. A three-dimensional shape with three faces is a cylinder.
A two dimensional shape with 3 sides or more is considered to be a polygon
A two dimensional shape would have 17 sides. For a three dimensional shape - assuming that sides are faces - the answer depends on the shape itself.
When two sides (called faces) of a 3-dimensional shape meet, they meet at an edge.
Any 2-dimensional shape has a vertex where two sides meet.Any 3-dimensional shape has a vertex where three or more faces meet.
A shape that has 10 sides (two dimensional) is called a decagon. A shape that has 10 faces (three dimensional) is call a decahedron.
An octagon is two dimensional and has eight sides.
you call a two dimensional shape with six sides a hexagon
A polygon; specifically a tetragon. A two-dimensional shape with four equal sides and four right angles is a square. A two-dimensional shape with two sets of equal sides and four right angles is a rectangle. A two-dimensional shape with two sets of equal sides and two sets of equal angles is a parallelogram. A parallelogram where each opposite angel bisects the shape is a rhombus. A two-dimensional shape with one set of equal, parallel sides and two sets of equal angles is a trapezoid. A three-dimensional shape with four triangular faces is a tetrahedron.
An 8 sided shape is an octagon
A decagon. A two-dimensional shape (plane figure, or polygon) which has ten sides is a decagon. A three-dimensional shape (polyhedron) which has ten sides (plane faces) is a decahedron.
