True or false? the blue radius is perpendicular to the green chord.

Option A. True.

Step-by-step explanation:

As we know form the radius and chord theorem if diameter or radius divides a chord in two equal parts then radius will be perpendicular to the chord.

Here chord in green color is divided in two equal parts 7.2 units each by radius in blue color.

Therefore by theorem radius of the circle will be perpendicular bisector of the chord.

Hence The statement given in the question is True.

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)
