Theory:

Step 1: Draw a line segment $$PA$$.

Step 2: Place the protractor on the line segment $$PA$$ and the mid point of the protractor at point $$P$$, as shown in the figure.

Step 3: On $$PA$$ from the right side of the protractor start counting from $$0°$$ in the ascending order (counter-clockwise direction) and finally mark a point $$Q$$ using a sharp pencil at the point between $$120°$$ and $$130°$$ showing $$125°$$ on the semicircular edge of the protractor.

Step 4: Remove the protractor and join $$PQ$$.

We get the required angle $$∠APQ$$ $$=$$ $$125°$$.
