Hey George, good to see you again. Here are the steps to construct the figure and find the required loci and measurements: a) i) Constructing triangle PQR Step 1: Draw a straight line and mark a point P on it. Step 2: Using a ruler, measure 7.5 cm from P along the line and mark point Q. So, |PQ| = 7.5 cm. Step 3: At point P, construct an angle of 135^. • Extend the line segment QP to the left of P. • Construct a 90^ angle at P, opening upwards from PQ. • Bisect the angle formed by the 90^ line and the extended line (to the left of P). This bisection will give a 45^ angle. The angle from PQ to this bisector will be 90^ + 45^ = 135^. Step 4: Along the 135^ line from P, measure 9 cm and mark point R. So, |PR| = 9 cm. Step 5: Join points Q and R with a straight line segment to complete triangle PQR. a) ii) Constructing Locus L_1 Step 1: Place the compass needle at P and open it to a radius greater than half the length of PQ. Step 2: Draw an arc above and below the line segment PQ. Step 3: Without changing the compass radius, place the needle at Q and draw another arc that intersects the first two arcs at two points. Step 4: Draw a straight line connecting these two intersection points. This line is L_1, the locus of points equidistant from P and Q. a) iii) Constructing Locus L_2 Step 1: Place the compass needle at Q and open it to a radius greater than half the length of QR. Step 2: Draw an arc above and below the line segment QR. Step 3: Without changing the compass radius, place the needle at R and draw another arc that intersects the first two arcs at two points. Step 4: Draw a straight line connecting these two intersection points. This line is L_2, the locus of points equidistant from Q and R. b) Locating point S Step 1: Identify the point where the lines L_1 and L_2 intersect. Step 2: Mark this intersection point as S. c) Joining SR Step 1: Draw a straight line segment connecting point S to point R. d) Measuring SRQ and PQR Step 1: Using a protractor, measure the angle SRQ (the angle at R formed by lines SR and RQ). Step 2: Using a protractor, measure the angle PQR (the angle at Q formed by lines PQ and QR). Since this is a construction problem, the final angle measurements depend on the accuracy of your physical drawing. You will need to measure these angles from your constructed diagram.
