Decide what AA actually requires
Triangle PQR has angles 55° and 85°. Triangle XYZ has angles 55° and 85°, matched to the same two vertices. No side length of either triangle is known. Is that enough information to conclude the two triangles are similar?
Correct.This lesson is now marked done.
Back to the lesson · Next lesson: Corresponding sides are in constant ratio →
Not quite.Try again, or ask for a hint.
Ask what freedom is left once two angles are pinned down, and whether a side length was ever part of that freedom.
