A dodecagon has 12 vertices.
It has 20 vertices or angles. * * * * * No! A dodecagon has 12 vertices. A polygon with 20 vertices is an icosagon.
The interior angles of a dodecagon sum to 1800 degrees.
The interior angles of a dodecagon sum to 1800 degrees.
By definition, a dodecagon has 12 sides and 12 internal angles
The interior angles of a dodecagon add up to 1800 degrees.
A dodecagon has 12 interior angles that add up to 1800 degrees.
A dodecagon has 12 vertices (corners).
The 12 interior angles of a dodecagon add up to 1800 degrees
The shape of the twelfth figure is a dodecagon. A dodecagon is a polygon with twelve sides and twelve angles. It is a regular dodecagon if all its sides and angles are equal. The interior angles of a regular dodecagon measure 150 degrees each.
A dodecagon has 12 interior angles. To find the sum of the interior angles of a dodecagon, you can use the formula ((n - 2) \times 180) degrees, where (n) is the number of sides. For a dodecagon, this calculation gives ((12 - 2) \times 180 = 1800) degrees, so the sum of all interior angles is 1800 degrees. Each interior angle in a regular dodecagon would then measure 150 degrees.
The interior angles of a dodecagon sum to 1800 degrees.
