#### Answer

The order in which the points of the triangles are listed identify the corresponding parts.

The triangles have the same angle measurements and same side length ratios, but different side length measurements. The points/letters on the triangles indicate how these two similar triangles are drawn to correspond with each other.
M and R, N and S, and P and T correspond with each other.
The triangles are drawn so that these points line up to have the the same angle measurements and side length ratios, making them similar.
