1.
Using ruler and compasses, construct the
(i) 30°
(ii) 15°

Answer 1

1) For 30° -

* Starting with a Ray :

1. Draw a ray AB. Let A be the vertex of the angle we're going to construct.

2 . Place the tip of the compass on A and draw an arc which cuts AB at some point (say X). Let's call this arc as Arc One. Retain this width of the compass for the remaining steps.

3 . Place the tip of the compass on X and draw another arc (call it Arc Two) which cuts Arc One at some point (say Y).

4 . Place the tip of the compass on Y and draw another arc (Arc Three) so as to cut Arc Two at a point (say Z) which is on that side of Arc Two which does not contain the point A.

5 . Connect the points A and Z with a straight line and extend it to form a ray AC.

The measure of the angle CAB is 30° . Erase any extraneous constructions if you so wish.

2) For 15° -

pls follow the same procedure
