Does the diagram give enough information to use the SAS Congruence Postulate Explain your reasoning D a

A

B

C

From the diagram you know that AB CB and DB DB

The angle included between AB and DB is ABD The angle included between CB and DB is CBD Because the included angles are congruent you can use the SAS Congruence Postulate to conclude that ABD CBD

Does the diagram give enough information to use the SAS Congruence Postulate Explain your reasoning H b
G E

F

You know that GF GH and GE GE However the congruent angles are not included between the congruent sides so you cannot use the SAS Congruence Postulate
