Question

constructing a 30 degree angle.​

Answer 1

Answer:

Bisecting angles without a protractor

Place the compass on the vertex of the angle (point B). Draw an arc across each arm of the angle.

Place the compass on the point where one arc crosses an arm and draw an arc inside the angle. ...

Use a ruler to join the vertex to the point where the arcs intersect (D).

Answer 2

Answer:

First of all we need to construct 60 degree too.....

And then we can construct 30 degree so ........

The answer is explained below and mark it as brainliest pls.....

Step-by-step explanation

60 degree construction first:-

Step 1:  Draw the arm PQ.

Step 2:  Place the point of the compass at P and draw an arc that passes through Q.

Step 3:  Place the point of the compass at Q and draw an arc that passes through P.  Let this arc cut the arc drawn in Step 2 at R.

Step 4; Join P to R. The angle QPR = 60 degree. As triangle PQR is a equilateral triangle.

Now ,30 degree construction :-

We know that:

So, to construct an angle of 30º, first construct a 60º angle and then bisect it.

Step 1:  Draw the arm PQ.

Step 2:  Place the point of the compass at P and draw an arc that passes through Q.

Step 3:  Place the point of the compass at Q and draw an arc that cuts the arc drawn in Step 2 at R.

Step 4:  With the point of the compass still at Q, draw an arc near T as shown.

Step 5:  With the point of the compass at R, draw an arc to cut the arc drawn in Step 4 at T.

Step 6:  Join T to P.  The angle QPT is 30º.

So this is how to construct 30 degree ........Hope it helps
