How many lines of symmetry do decagons have?
Decagons have 10 lines of symmetry i dont know where
Are two hexagon always similar to each other?
No. Two regular hexagons are always similar to each other, but two random hexagons are not necessarily similar.
How many rotational symmetry does decagon have?
A regular decagon has rotational symmetry = 10.For irregular decagons, it could be less (either 2 or none.)
How many pairs of parallel lines does a decagon have?
A regular decagon will have 5 pairs of parallel sides, however, irregular decagons can have no parallel sides.
Are any two regular polygons with the same number of sides similar?
Yes, regular polygons will have all sides equal length, and all angles the same. If two polygons of the same number of sides are 'regular' then those two polygons will be similar (they may be scaled, for example).
Can a decagon tessellate?
yes definitely you can tesselate a regular haxagon
What shapes are similar to a decagon?
There are a number of polygons that are similar to it but if you mean things that look like decagons than nonagon, undecagon, dodecagon, and octagon.
Must the corresponding angles of two similar regular polygons be equal?
All angle of two similar regular polygons must be equal.
Are two regular polygons always similar?
no.
How do you find the area of a decagon?
measure the perimeter then measure from the EXACT center to a side multiply this only works on regular decagons!

How many pairs of parallel lines does a decagon have?
A regular decagon will have 5 pairs of parallel sides, however, irregular decagons can have no parallel sides.
What are the kinds of dodecagon?
There are many ways of classifying decagons. There are convex or concave dodecagons. Or they can be classified as regular, equiangular-irregular, equilateral-irregular or fully irregular.
How many faces have pairs of parallel edges in a decagonal based prism?
If the prism is based on regular decagons and it is a right prism, all 12 faces.
Are any two regular polygons with the same number of sides similar?
Yes, regular polygons will have all sides equal length, and all angles the same. If two polygons of the same number of sides are 'regular' then those two polygons will be similar (they may be scaled, for example).
