Question

In the figure given below, AB || CD and
BC || QP If Angle ABC = 40° , Find measures of. ​

Answer 1

Step-by-step explanation:

a) since, abc=40°

bcd=40°

abc = bcd(alt. interior angle)

d) bcd=qrd=40°(corresponding angles)

b) now,

crq+qrd=180(linear pair of angles)

crq+40°=180°

crq=180°-40°

crq=140°

C) prd=crq=140°(vertically opposite angles)
