One example is building an A-frame house. The bar of the frame being parallel to the ground leads to similar triangles, and the dimensions of the frame will reflect that similarity.

The height of a tall building or tree can be calculated using the length of its shadow and comparing it to the shadow of an object with a known height.

Every time a scale model is used for something, it is an application of similar figures.
