Circles and ratio

a. I would assume that you would name the circle B since it is the midpoint.

b. A radius would be BE since it is halfway through the circle.

c. A diameter would be AD since it goes through the entire circle.

d. Another diameter would be FE since it, once again, goes through the entire circle.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
