Construct the angle of the measurement:
1. 22 `(1°)/2`
Solution
Steps of construction:
Step 1: Draw a line segment AB
Step 2: with center A and any radius, draw an arc which intersects AB at C
Step 3: with center C and same radius, draw an arc which intersect previous arc at D
Step 4: with center D and same radius, draw an arc which intersects arc in (2) at E.
Step 5: with center E and D and radius more than half of ED, draw arcs intersecting each other at F.
Step 6: Join FA which intersects arc in (2) at G
Step 7: with center G and C and radius more than half of GC, draw arcs intersecting each other at H
Step 8: Join HA which intersects arc in (2) at 1.
Step 9: with centers I and C and radius more than half of IC, draw arcs intersecting each other
Step 10: Join JA
∴ `∠`JAB = 22 `(I°)/2`
