Answer 1

Answer:

(1.) no

(2.)no

(3.)no

Step-by-step explanation:

(1.) because aob + boc is not equal to 180°. ie, 85+80=165° is not equal to 180°

(2.) (vertically opposite angles should be equal)

aob is not equal to boc. ie, 85° is not equal to 125°

(3.)aod+doc+boc+aob=360°

aod+125°+80°+85°=360°

aod=360°-290°

aod=70°

aod+doc=180°(linear pair)

70°+125°=180°

195° is not equal to 180°
