By which property are ΔQST and ΔQUT congruent to each other?
AAS
SSS
RHS
SAS
In ΔQST and ΔQUT ∠SQT = ∠TQU [given] ∠QST = ∠QUT [given] QT=QT [common] ∴ΔQST and ΔQUT are congruent by AAS congriency rule.
In the construction of the bisector of a given angle, as shown in the figure below
ΔBEF ≅ ΔBDF by which congruence criterion?
In fig., if AB = AC and BD = DC. ΔABD and ΔACD are congruent by which criterion.
