Question

please answer this question

Answer 1

ans.3. letter t
ans.4. 5 lines of symmetry are present in a regular pentagon

Answer 2

ANSWER 1


SOME INFORMATION



=> Rotational symmetry


Rotational symmetry in capital letters describes a property in which the letter looks the same after being rotated. 



IN ALPHABET THE LETTER WHICH SHOW
THIS ARE =>



Capital letters that have rotational symmetry are: Z, S, H, N and O.




Now discuss about order of symmetry



1 order. one symmetry in letters=>

The letter O has rotational symmetry on the order of one, because after being rotated by 90 degrees, it still looks the same.



2 order two symmetry =>

The letters Z, S, H and N, when rotated 180 degrees clockwise or counterclockwise, will look the same after rotation completion. This is called rotational symmetry on the order of two,




=>NOW YOUR ANS

In. MATH word there is

H, have. order 2 rotational symmetry.






ANSWER (2)



A regular pentagon have 5 sides and 5 number line a summetry


NOTE

The number of lines of symmetry in a regular polygon is equal to the number of sides.
