1. How to draw 15 degree angle
Construction of angles 15 degree angle with compass with main point of Construction
(a) Draw a line segment
(b) Take compass and pencil
(c) Draw the arc
Now put the compass nib on C point then draw a arc. We give this arc name point D.
(d) From point C and D draw the arc one by one.
from point D
from point C
(e) where this two arc intersection each other, we give point E.
(f) Then draw a line from E to A, by using scale and pencil.
(g) Cut the arc from point F and C.
from point F
From point C
(h) where this two arc intersection each other, we give point G.
(i) Then draw a line from G to A, by using scale and pencil.
(j) We get a angle of 15 degree.
