Hint: A triangle is a three sided quadrilateral and to construct a triangle one needs to draw a line segment and suppose it to be the base of the triangle. To construct a triangle one needs a protractor or a compass, a ruled scale.

We have the measure of angle B, therefore using the protractor we will make the $\angle PBC$ of measure equal to the $\angle B = {40^ \circ }$ and extend the ray .
