3o decagons
A pentagon has 5 sides, and a decagon has 10 sides. Therefore, 4 decagons would have (4 \times 10 = 40) sides. Adding the sides together, 1 pentagon and 4 decagons have a total of (5 + 40 = 45) sides.
it is part of geometry
all decagons have 1440 degrees
A pentagon has five sides, and a decagon has ten sides. So 3 pentagons and 5 decagons have (35)+(510) = 65 sides altogether
Decagons have 10 lines of symmetry i dont know where
For anyone who is not a synesthete, a decagon has no specific colour. Individual synesthetes will see decagons in different colours.
Yes 2 ten sided regular decagons can be similar or congruent to each other
They are decagons.
There are decagons which will tessellate.
