A decagon.
A polygon has as many angles as sides, so a polygon with 10 sides (decagon) would have 10 angles.
A polygon is a closed figure of three or more sides. A regular polygon is a figure with straight sides, each side of equal length and all internal angles equal to each other. 3 sides = triangle 4 sides = square 5 sides = pentagon 6 sides = hexagon 7 sides = heptagon 8 sides = octagon 9 sides = nonagon 10 sides = decagon
A decagon has 10 sides. It also have 10 angles.
decagon
A decagon.
If the sides are all equal, and opposite sides are parallel, then the angles are all equal (72º) and it is a 'regular hexagon'. A six sided plane figure is called a hexagon, as "hex" means "six."
Decagon, if a plane figure or decahedron, if a solid.
10 sides and 10 angles
A polygon with 10 sides and 10 angles is called a decagon.
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.
A polygon has as many angles as sides, so a polygon with 10 sides (decagon) would have 10 angles.
A Regula Convex decagon has 10 equal sides and 10 angles with each angle being 144 degrees. There are also convex decagons that have ten angles but some of them may be inscribed in the figure. All 10 sided figures though are known as a decagon.
10 A decagon is a plane (2-d) figure and so it has only one face. It has 10 sides and 10 vertices.
Triangle = 3 sides 3 angles Square = 4 sides 4 angles Hexagon = 5 sides 5 angles Pentagon = 6 sides 6 angles No certain name for 7 sides and 7 angles Octagon = 8 sides 8 angles Nonagon = 9 sides 9 angles Decagon = 10 sides 10 angles
A decagon has 10 sides, and 10 angles. The sum of the interior angles of a decagon is (10-2)×180° = 1440° In a regular decagon all the angles are congruent at 1440° ÷ 10 = 144°
