Given that $p:$ If a quadrilateral is equiangular, then it is a rectangle, $q:$ If a quadrilateral is a rectangle, then it is equiangular,are some pairs of statements . Combine the pair of these statements using if and only if

Given that  $p:$ If the sum of the digits of a number is divisible by $3$, then the number is divisible by $3$,and  $q:$ If a number is divisble by $3$, then the sum of its digits is divisible by $3$,  are some pairs of statements.  Combine these pair of stayements using "if and only if"

Given below are some pairs of statements. Combine each pair using if and only if:

$p:$ A quadrilateral is a parallelogram if its diagonals bisect each other.

$q:$ If the diagonals of a quadrilateral bisect each other, then it is a parallelogram.

Given below are some pairs of statements. Combine each pair using if and only if:

$p:$ If $f\left(a\right)=0$ then $\left(x-a\right)$ is a factor of polynomial $f\left(x\right)$

$q:$ If $\left(x-a\right)$ is a factor of polynomial $f\left(x\right)$ then $f\left(a\right)=0$
