Answer:
To construct a Congruent Angle
→Draw a semicircle from point Q, which intersects the two rays QP and QR ,at point S and T.Keeping the compass at point R having the same width draw a semicircle which cuts the ray QR at point M.
→Now, Measure the length of arc ST with the Help of Compass.
→Now, Putting the compass at Point M, marc arc on the semicircle ,that is N.
→Draw a ray from point R passing through N.
That is required Congruent Angle.
Option B , is most Appropriate to Construct Congruent Angle at R.where we have drawn semicircle from point Q.
