What is a shape with ten sides and not a decagon?
In 2-d, the naming of polygons is such that a 10 sided shape is a decagon. Even if it is a 5-pointed star shape, it is a decagon. A concave decagon (rather than convex) but still a decagon. In 3-d, a decahedron, possibly, with the term "sides" being used for "faces".
What shape has 10 verticies?
Decagon
What is a 10 sided polygon called?
The anwser is a Decagon.
How many sides has a do-decagon have?
Its not a do-decagon its a dodecahedran!!
What kind of polygon is a star?
Decagon
Is a hen decagon concave or convex?
It can be convex or concave.
Is a do-decagon a convex sometimes always or never?
Sometimes.
What is the sum of the measures of the exterior angles of a convex decagon?
The sum of the exterior angles of ANY polygon, convex or concave, is 360 degrees.
What is the sum of interior angles of a convex decagon?
Not only convex, but all decagons:decagons have 10 sides implies Sum = (10-2)*180o = 1440o.

How lines of symmetry does a decagon have?
None are guaranteed.If it is a regular decagon (convex, with all side lengths equal and all angle measures equal), then there are 10 lines of symmetry.
What has Ten sides and ten 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.
How many Acute angles does a decagon have?
It depends on whether or not the decagon is a perfect decagon or a complex decagon. However, a perfect decagon has no acute angles.
What do you call a 10 side polygon?
decagon
What shape has 10 verticies?
Decagon
What the sum of the measures of the interior angles of each convex polygon 10-gon?
Sum of interior angles of a n-gon is 180*(n-2) So for a 10-gon (decagon), the sum would be 180*8 = 1440 degrees. That is true whether the polygon is convex or not (as long as its sides do not intersect).
What is a 10 sided polygon called?
The anwser is a Decagon.
