CYU #2

Is there enough information to prove these triangles are similar? Choose all that are correct.

Not by SSS

because

no side lengths given

Yes by AA~

because

∠ABE≅∠BCD\angle ABE\cong\angle BCD

and

∠EAB≅∠DBC\angle EAB\cong\angle DBC

Not by SAS

because

no side lengths given

Yes by ASA

because

∠ABE≅∠BCD\angle ABE\cong\angle BCD

∠EAB≅∠DBC\angle EAB\cong\angle DBC

and BE≅CDBE\cong CD

CYU #6

Is there enough information to prove these triangles are similar? Choose all that are correct.

Not by AA~

because

there are NO congruent angles

Not by SSS

because

there are NO congruent sides

Yes by SAS

because

1520=2432\frac{15}{20}=\frac{24}{32}

and

∠LNM≅∠PNO\angle LNM\cong\angle PNO

Not by SAS

because

m∠MLN≠m∠OPNm\angle MLN\ne m\angle OPN
