If two angles of one triangle are congruent to two angles of another triangle, then the two triangles are similar. This similarity means that the corresponding sides of the triangles are proportional, which is super handy when you need to find missing lengths or analyze similar figures in geometry.

In real-world terms, think about how scaling up a model of a building works! If you know two angles of the model and they match with the actual building’s angles, you can figure out how tall (or wide) the real building is compared to your model—just by keeping everything proportional, thanks to the Angle-Angle criterion!
