Question

how to construct a reflex angle

Answer 1

To draw a reflex angle (i.e. angle greater than 180º and less than 360º), proceed as follows:

Subtract the reflex angle from 360º. Then draw the resulting angle as described earlier.

The required angle is outside the one that has been drawn.

Mark the angle with a small arc.

Label the angle.

hope this helps you

Answer 2

First draw a straight line of 180 degree and then from downward draw your required angle
Let angle be 280 then 280-180= 100 first draw. 180 degree and from downward draw 80 degree it's very easy
