Answer:
Their sides must be in the same ratio and their angles must be equal.
Step-by-step explanation:
If two polygons are similar their sides must be in the same ratio and their angles must be equal.
e. g. -
If ABCDEF and GHIJKL be the two polygons,
then,
and,
∠ABC = ∠GHI ; ∠BCD =∠HIJ ; ∠CDE = ∠IJK ; ∠DEF =∠JKL ; ∠EFA =∠KLG;
∠FAB = ∠LGH .
Hey there, Lets solve this problem together.
The First step is to line up the numbers.
<span>We calculate </span>

Since we get a negative number in the next column, we must take 1 from the next column and carry it over to this column. Now the number will be changed to 10.
We calculate
, and the result is

Therefore,
Answer:
x+9
Step-by-step explanation:
the perimeter of any polygon is the sum of all the sides
The correct answer is Choice A I hope it helps :)
