Question

please give me answer correctly and plz correct information and give reason 1 st problem​

Answer 1

Answer:

yes it is because it is the sum of cost interior angle , like 70+110=180, therefore they are equal

Answer 2

Answer:

yes

Step-by-step explanation:

in ∆ABC and ∆PQC

angle PQB+angle PQC=180(straight line)

110°+PQC=180

PQC=180-110

PQC=70°

Angle ABC=70°

hence,

Angle ABC=AnglePQC

therefore by cointerior angles theorem

PQ||AB

in∆ABC &∆PQC

angle ABC=anglePQC

angle C=angle C

∆ABC~∆PQC(AA Similarity criterion)

Hence Proved.
