Yes, all regular decagons are similar because they have the same shape but can differ in size. Similarity in polygons means that corresponding angles are equal and the lengths of corresponding sides are proportional. Since all regular decagons have equal angles (144 degrees) and their sides are all the same length relative to their size, any regular decagon can be transformed into another through scaling.
What else can I help you with?
If the areas of two similar decagons are 625 ft2 and 100 ft2 what is the ratio of the perimeters of the decagons?
The areas of two similar decagons are in the ratio of 625 ft² to 100 ft², which simplifies to 6.25:1. Since the ratio of the perimeters of similar shapes is the square root of the ratio of their areas, we take the square root of 6.25, which is 2.5. Therefore, the ratio of the perimeters of the decagons is 2.5:1.
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 two regular decagons similar?
Yes 2 ten sided regular decagons can be similar or congruent to each other

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.
Can a decagon tessellate?
yes definitely you can tesselate a regular haxagon
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 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 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.

How many sides do 4 pentagons and 5 decagons have in all?
60
Are all pentagons are similar?
NO! Only REGULAR Pentagons. All equilateral triangles are similar!!!
