Solution
So, to construct an angle of
30
∘
, first construct a
60
∘
angle and then bisect it. For this, we would apply the following steps:
Step 1: Draw the arm
P
Q
.
Step 2: Place the point of the compass at
P
and draw an arc that passes through
Q
.
Step 3: Place the point of the compass at
Q
and draw an arc that cuts the arc drawn in Step 2 at
R
.
Step 4: With the point of the compass still at
Q
, draw an arc near
T
as shown.
Step 5: With the point of the compass at
R
, draw an arc of the same measure to cut the arc drawn in Step 4 at
T
.
Step 6: Join
T
to
P
.
The angle
Q
P
T
is
30
∘
.
