Question

$\overline{\mathit{\text{OR}}}$is a common side of two congruent quadrilaterals.

Complete: quad. $\text{NERO}\cong$quad $\underset{¯}{?}$.

Short answer

Two points of $F$such that $quad\mathit{\text{NERO}}\cong quad\mathit{\text{MARO}}$.

Step-by-step solution

Step 1. Consider the diagram.

Here, both the quadrilaterals are congruent and$\overline{OR}$ is the common side of the two congruent quadrilaterals.

Step 2. State the explanation.

It is known that when two quadrilaterals are congruent then their corresponding sides and angles are equal.

So, here,

$\angle N\leftrightarrow \angle M$,$\angle E\leftrightarrow \angle A$,$\angle R\leftrightarrow \angle R$,$\angle O\leftrightarrow \angle O$.

Step 3. State the conclusion.

Therefore,$quadNERO\cong quadMARO$.
