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.
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.
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 degrees are in a irregular decagon?
all decagons have 1440 degrees
Are all pentagons are similar?
NO! Only REGULAR Pentagons. All equilateral triangles are similar!!!
Are two regular decagons similar?
Yes 2 ten sided regular decagons can be similar or congruent to each other
Can a decagon tessellate?
yes definitely you can tesselate a regular haxagon
Is regular polygons also similar?
-- All regular (equilateral) triangles are similar. -- All squares are similar. -- All pentagons are similar. -- All hexagons are similar. . . . etc. Any regular polygon is similar to all other regular polygons with the same number of sides.

How many sides does a regular decagons have?
It still has ten sides, same as a normal decagon. "Irregular" simply means that all the sides and angles of the decagon are not congruent.
Are all regular octagons similar?
Yes, all regular octagons are similar. All regular x-gons are similar, as long as the x is constant, as they must have the same angle measures to be regular.

How many sides do 4 pentagons and 5 decagons have in all?
60

NO! Only REGULAR Pentagons. All equilateral triangles are similar!!!
How many lines of symmetry do decagons have?
Decagons have 10 lines of symmetry i dont know where
