Question

When rotated about its center, a regular decagon has ( ? )

rotational symmetries. In addition to rotational symmetry, a regular decagon has
( ? ) lines of reflectional symmetry.

Answer 1

The answer is 10 rational symmetries and 10 lines

Step-by-step explanation:

decagon has 10 sides.

Answer 2

When rotated about its center, a regular decagon has ( 10 )

rotational symmetries. In addition to rotational symmetry, a regular decagon has

( 10 ) lines of reflectional symmetry.
