Writing the letters in the correct order when discussing the similarity of triangles is important because it helps to clearly identify corresponding sides and angles between the two triangles. When comparing similar triangles, it is essential to match up corresponding parts to show that they are in proportion to each other. This helps to determine if the triangles are similar based on the properties of similar triangles, such as the angles being congruent and the sides being in proportion. Writing the letters in the correct order ensures that there is no confusion in identifying corresponding parts and accurately determining similarity.
