Question

If P and Q are fixed points, the locus of R so that <PQR=50° is:-

1. a line perpendicular to PQ
2. a whole cirlce
3. a line parallel to PQ
4. part of 2 circles​

Answer 1

1. a line perpendicular to PQ

Explanation:

The angle formed will be acute angle as the angle is less than 90 degrees. This line will be perpendicular to PQ . The points connected on the locus will form a semi circle. To draw the angle vertex is identified and then a line is drawn on it to form an angle.
