Chapter 4.1, Problem 20WE

To determine

From the given figure, $quadNERO\cong$

Answer to Problem 20WE

  $quadNERO\cong quadMARO$

Explanation of Solution

Given information : We have two congruent quadrilateral as shown in figure.

Given that $\overline{OR}$ is a common side of two congruent quadrilaterals.

We know that when two quadrilaterals are congruent then their corresponding sides and angles are equal.

So, here

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

Therefore,

  $quadNERO\cong quadMARO$
