 Hello and welcome to the session. In this session we discuss the final question that says, there are three straight lines P2PR and XY. Find the position of a point equidistant from the straight lines P2 and PR at a distance of 2 centimeters from XY. Before moving on to the solution, let's discuss some useful loci. First we have locus of a point equidistant from two intersecting is the bisectors between the given. Also locus of a point at a given distance straight line to the at the given distance on the given line. Key idea that we use in this question. Let's proceed with the solution now of the three straight lines P2PR and XY. The P2 and PR are two intersecting straight lines and we have to find the position of a point equidistant from the straight lines P2 and PR and is at a distance of 2 centimeters from the straight line XY. So let's see what all conditions are given to us for first condition. Position of a point is given as that that point should be equidistant from the straight lines P2PR at a distance of 2 centimeters from the straight line two conditions given to us. Now let's start with the construction. Now that we know that the locus of a point equidistant from two intersecting straight lines is the bisectors of the angles between the given intersecting straight lines and since we have the condition that we have to find the position of a point which is equidistant from the straight lines P2 and PR. So for this we will draw the angle bisector of the angle between the straight lines PQ and PR. That is we have to draw the angle bisector of the angle QPR. We have to draw the bisector of the angle QP to assess that the centimeters from the straight line we know that the locus of a point to the line XY two centimeters. We draw two centimeters which of these lines are parallel to two centimeters from XY. Now we are done with the second condition also. Let the line L1 intersect the angle bisector of angle QPR, a sector of angle QPR be at the required points. That is intersection required points, the solution of this question.
