It can but it need not.
A 'concave decagon' is a ten-sided shape with every other corner pushed in towards the centre. It forms a regular five-pointed star.
a regular star
I think regular. * * * * * Only if you ignore all the points where the sides cross one another.
A regular six pointed star.
ofcourse no, quadrilateral means its a poligon with 4 sizes, like square, rectangle, rhombus, trapezium, etc... And Decagon, means its a poligon with 10 sizes. a decagon is a polygon with ten sides. a quadrilateral is a polygon with four sides. "deca" = 10 "quadri" = 4
the answer is a thing that has 8 sides lol
poligon
Yes. A star is a regular polygon.
yes
To the best of my knowledge, it isn't. It is a regular star in a regular galaxy which will regalarly collide with Andromeda in a billion years.
if the no of diagonals is "n" then the no of sides of the poligon can be given by the formula 2n/n(n-3).
135
Yes, the sun is a regular star. It is classified as a yellow dwarf star and is in the main sequence phase of its life cycle.

Betelgeuse is a semi-regular variable star, meaning it does not have a consistent period like a regular variable star. Its brightness fluctuates irregularly over periods of months to years.
