Question

Construct the angle of the measurement:

1. 15°

Answer 1

Steps of construction:
Step 1: Draw a line segment AB
Step 2: with center A and any radius, draw an arc which intersects previous arc 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 C radius more than half of DC draw arcs intersecting each other at E
Step 5: Join EA which intersects arc in (2) at F.
Step 6: With centers F and C and radius more than `1/2`FC draw arcs intersecting each other
Step 7: Join GA
∴ `∠`GAB =15°
