key idea

Congruent shapes have the same size and shape. In congruent shapes, all pairs of corresponding angles are congruent and all pairs of corresponding sides are congruent.

Look at the sides. Find the lengths of all the sides.

OPQR is a rhombus. All the sides are the same length. OP and RO are both 51 mi.

VWXY is also a rhombus. All the sides are the same length. VW and WX are both 47 mi.

There is no side in the right shape congruent to OP in the left shape. So, the shapes are not congruent.
