Answer 1

@LegendarySadist

Answer 2

the word bisects, means to cut into 2 equal parts... so find half of angle AOD, which is the measure of BOF

Answer 3

@campbell_st its a acute angle so it has to be less than 90

Answer 4

yes but look at the diagram... AB and CD intersect at right angles that is a fact you need to use...

Answer 5

\[\frac{ 90 }{ 2 }=answer\]

Answer 6

there you go... someone always gives the answer

Answer 7

it cant be a fraction :p

Answer 8

so if 1 angle at the point of intersection of AB and CD is shown as a right angle... all 4 angles at the intersection are right angles...

remember bisect means to cut into 2 equal parts..

Answer 9

what is half of 90...?

Answer 10

@campbell_st 90 / 2 = 45

Answer 11

@campbell_st 90 / 2 = 45
