answer
a,b, and d
explanation
a reflection angle is more than
![\pi \: radians](/tex.php?f=\pi \: radians)
but less than;
![2 \pi \: radians](/tex.php?f=2 \pi \: radians)
an angle that measures
![\frac{4 \pi}{3} \: radians](/tex.php?f= \frac{4 \pi}{3} \: radians)
is a reflex angle.(true)
an angle that measures less than
![\frac{\pi}{2}](/tex.php?f= \frac{\pi}{2} )
is acute.(true)
provided we are considering angles greater or equal to zero.
an acute angle lies in the range.
![0 \leqslant \theta \: < \frac{\pi}{2}](/tex.php?f=0 \leqslant \theta \: < \frac{\pi}{2} )
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)
