Assuming you mean a pentagon - not penagon, a 3-dimensional pentagon is a dodecahedron which has 12 faces.
Three pairs.
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.
2 dimensional (plane) figures can have three or more straight edges as sides. 3 dimensional (solid) figures can have four or more plane sides (faces). They can have fewer sides if the sides are not straight.
An icosagon is a two-dimensional polygon, not a three-dimensional figure. An icosagon has 20 sides - while an icosahedron has 20 faces.
A sphere is a round object. It has no sides. The object is 3-D. (Three Dimensional)
5 sides
A pentagon has 5 sides.
it has 5 sides and 5 angles
Three pairs.
2-dimensional shapes, with three straight sides have three vertices.
there are 6 sides : top and bottom = 2 + 4 sides = 6
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.
2 dimensional (plane) figures can have three or more straight edges as sides. 3 dimensional (solid) figures can have four or more plane sides (faces). They can have fewer sides if the sides are not straight.
Many kites have four sides, like quadrilaterals. However, quadrilaterals are two-dimensional figures; kites are three-dimensional.
An icosagon is a two-dimensional polygon, not a three-dimensional figure. An icosagon has 20 sides - while an icosahedron has 20 faces.
A sphere is a round object. It has no sides. The object is 3-D. (Three Dimensional)
An equilateral triangle has sides and angles. There are 3 sides in any triangle. Edges are in three dimensional figures.
