Bài 5:

a: Ax//By

=>\(\hat{A_1}+\hat{B_1}=180^0\) (hai góc trong cùng phía)

=>\(\hat{B_1}=180^0-140^0=40^0\)

b: Ta có: \(\hat{B_1}+\hat{B_2}=\hat{ABC}\) (tia By nằm giữa hai tia BA và BC)

=>\(\hat{B_2}=90^0-40^0=50^0\)

c: Ta có: \(\hat{B_2}+\hat{BCz}=50^0+130^0=180^0\)

mà hai góc này là hai góc ở vị trí trong cùng phía

nên By//Cz

=>Ax//Cz

d:

Gọi O là giao điểm của Cm và Qn

PQ là đường trung trực của AB

=>PQ⊥AB

mà BA⊥BC

nên PQ//BC

=>\(\hat{PQC}+\hat{BCQ}=180^0\)

=>\(2\left(\hat{OQC}+\hat{OCQ}\right)=180^0\)

=>\(\hat{OQC}+\hat{OCQ}=90^0\)

=>ΔOCQ vuông tại O

=>Cm⊥Qn tại O
