Do corresponding sides of similar triangles have the same measure?

No, corresponding sides of similar triangles do not have the same measure; instead, they are proportional. This means that while the lengths of the corresponding sides differ, the ratiOS of their lengths remain constant. For example, if one triangle has sides of lengths 3, 4, and 5, and a similar triangle has sides of lengths 6, 8, and 10, the corresponding sides maintain the same ratio (2:1).
