we can measure reflex angle in two ways ;

• by using a protector
• aur by adding to an acute obtuse angle to make it a 360 degree full circle .

three fourth turn off anything gives a reflex angle that equal to zero point 0.75 X 360 ° = 270 ° .

how can we draw a reflex angel ?

• subtract reflection angle from 360 degree then draw the resulting angle .
• the required angle is outside that one that has been drawn
• mark the angle with a small and label or name the angels

A example of reflex angel ?

the reflex angle A what is equal to 225 degree or 180 degree + 45 .
