प्रश्न
Using ruler and compasses, construct the following angle:
15°
उत्तर
Steps of Construction:
(i) Draw a line segment BC.
(ii) With centre B and a suitable radius draw an arc meeting BC at P.
(iii) With centre P and with the same radius cut off the arc at Q.
(iv) Taking P and Q as curves, draw two arcs intersecting each other at D and join BD.
(v) With centre P and R, draw two more arcs intersecting each other at S.
(vi) Join BS and produce it to A.
Then ∠ABC = 15°.
