Step-by-step explanation:
- step 1 :Draw a ray OY.
Then, take O as the centre and any radius, mark a point A on the arc ABC.
- Step 2: Now, taking A as the centre and the same radius, mark a point B on the arc ABC.
- Step 3: Take B as a centre and the same radius, mark a point C on the arc ABC.
- Step 4: Now, taking C and B as centre one by one, draw an arc from each centre intersecting each other at a point X.
- Step 5: X and O are joined and a ray making an angle 90^{\circ} with OY is formed.
Let the arc AC touches OX at E
- Step 6: With A and E as centres, 2 arcs are marked intersecting each other at D and the bisector of angle XOY is drawn.
