Exercise 40 Page 307

Be careful with the units of measure.

Yes, AB≅ CD.

Practice makes perfect

To determine if two segments are congruent or not, we need to check if their lengths are the same. In our case, we are told that AB=100 kilometers and CD=62 miles. It would seem that they are not congruent. However, let's take a look at the given scale.

According to the scale, 100 kilometers and 62 miles both represent the same length. Therefore, we can conclude that AB≅ CD.
