Question is in the picture

SAS

SSA

SSS

not congruent

Answer 1

QU =AD

QD=AU

DU is a common side of the triangles QUD and ADU,

so all three sides of these triangles are congruent, so we need postulate SSS.

Answer is SSS.

Answer 2

SSS is the answer because the parallel sides are congruent and the line that divides the shape is reflexive and makes it congruent to itself...
