how can we measure reflex angle?
to measure the angles u should take a protacter..
u know that the straight line has a measure of 180 degree.
then measure the angle after 180 degree by rotating your boook or by rotating your protactor downwards ..
then what your ans comes +it with 180 degree ..
u will get your ans..
A protractor can be used to measure the size of an acute angle (between 0º and 90º) and an obtuse angle (between 90º and 180º).
Now, we will use a protractor to measure the reflex anglePQR.
To measure the reflex anglePQR, extend the armPQtoAto form anglePQAwhich is a straight angle. Then measure the size of the angleAQRand add 180º.
