1. A truss has been designed to support the roof of a commercial structure, according to the specifications given in the diagram below. Point Q is located at the midpoint of the truss member from point P to point R. All dimensions are in meters. Note the symmetry of this shape. R P 4 S 4 T 4 4 5 Use Similar Triangles and the Pythagorean Theorem to find the exact lengths of all four truss members specified below. Then use a calculator to approximate the lengths to the nearest tenth. Show all your work clearly in the space below. Identify the truss members according to their joints as PQ, QR, QS, SR.
