प्रश्न
Draw a line segment AB = 6 cm. Without using set squares, draw angle OAB = 60° and angle OBA = 90°. Measure angle AOB and write this measurement.
उत्तर
Steps of construction:
- Draw a line segment AB = 6 cm
- At A, draw a ray making an angle of 60° with the help of a compass.
- At B, draw another ray making an angle of 90° which meet each other at O.
Now on measuring ∠AOB, it is 30°
