Use triangle congruence and similarity criteria to solve problems and prove geometric relationships.

Solve an indirect measurement problem with triangle similarity

Problem

Use similarity to solve this scale-model measurement problem: A model uses a \(1:50\) scale, with \(\text{model}~\text{length}~:~\text{actual}~\text{length}\). If the model height is \(6~\text{cm}\), what is the actual height?
