Give the measure of the angle between the two given sides (i.e. the included angle).

Reason: Two sides and the included angle determine a triangle uniquely by SAS congruence. (If instead you give a non‑included angle (SSA) there can be 0, 1 or 2 solutions — the ambiguous case.)

(Also, giving the third side length (SSS) would likewise guarantee a unique triangle.)
