Sammy Murphy · Answer 1

True

Step-by-step explanation:

Yes, We can use the congruent triangles and CPCTC to measure distances, such as the distance across a river indirectly.

For example: One of Napoleon's officers used the congruent triangles to estimate the distance across the river. On the riverbank, the officer stood up straight and he lowered the visor of his cap until the extreme thing he could see was the edge of the opposite bank. He then turned and noted the spot on his side of the river that was in line with his eye and the tip of his visor.

Using the two triangles, he made them congruent. Thus, it is true that congruent triangles and CPCTC can be use to measure the distances.
