Question

Write the inverse of the conditional statement. If a shape is a rhombus, then it has four congruent sides.

Answer 1

You write the inverse of a conditional statement by negating both the hypothesis and the conclusion.

So, the inverse of

$p\implies q$

is

$\lnot p \implies \lnot q$

So, in your case, the inverse of your statement is

If a shape is not a rhombus, then it doesn't have four congruent sides.
