how to construct an angle of measure 150 degrees???......

Hi Akshyata!

Here are the steps to construct an angle of measure 150°.

**Step 1:**Draw a line

*l*and mark a point P on it. Now taking P as centre and with a convenient radius, draw a semi-circle which intersects line

*l*at Q and R.

**Step 2:**Taking R as centre and with the same radius as before, draw an arc intersecting the previously drawn arc at S.

**Step 3:**Taking S as centre and with the same radius as before, draw an arc intersecting the arc at T (see figure).

**Step 4:**Taking T and Q as centre, draw arcs of same radius to intersect each other at U.

**Step 5:**Join PU which is the required ray making 150° with line

*l*i.e. ∠UPR = 90°.

Hope! This will help you.

Cheers!
