Answer 2

Answer:

90 Degrees:-

Draw the arm PA.

 Place the point of the compass at P and draw an arc that cuts the arm at Q.

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

With the point of the compass at R, draw an arc of radius PQ to cut the arc drawn in Step 2 at S.

With the point of the compass still at R, draw another arc of radius PQ near T as shown.

 With the point of the compass at S, draw an arc of radius PQ to cut the arc drawn in step 5 at T.

Join T to P. The angle APT is 90º.

180 Degrees:-

Draw a straight line which will be the arm of angle.

Put a dot at one end of the line.  

Now place the center of the protractor above the dot or vertex and match the baseline of the protractor along with the arm of the angle.

Mark the angle 180 degrees with a dot.
