The average age of cars on the road in the United States follows a normal distribution with a mean of 11.9 years and a standard deviation of 3.7
years. Approximately 20% of cars on the road will be over what age in
years?

This is true

Think of two houses. If we say "the houses are identical" then the corresponding pieces must be the same (eg: the doors must be the same type out of the same material). In this analogy, the houses are the triangles, which are the overall structures. The doors are the angles since they are pieces of the overall structures. This is what CPCTC is saying

CPCTC = Corresponding Parts of Congruent Triangles are Congruent

Once again, the final answer is true.
