What is the order of rotational symmetry for a rhombus

In general, a rhombus' diagonals have different lengths.  This limits the rotational symmetry order to be 2, namely, it gets back to the same shape by rotating 180 degrees. There is a special kind of rhombus where the diagonals have equal lengths, in which case the rhombus has order of rotational symmetry of four.  We also call this special kind of rhombus a square.

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
