"If two sides and an angle of one triangle are equal to two sides and an angle of another triangle,then the two triangles must be congruent." Is the statement true? Why?
(B) The statement is false. For two triangles to be congruent by the $SAS$ (Side-Angle-Side) congruence rule,the angle must be the included angle between the two sides. If the angle is not the included angle,the triangles are not necessarily congruent.
