C,BC, be the three given sidesof the triangle. 1. Take any side, sayAB, and from A as a centre,with the radius AC, describean arc of a circle. X 2. From B, as a centre, with the radius BC, describeanother arc, cutting the first. 4. From the point of intersection C, draw the straightlines CA, CB ;… … Solution. Let AB, AC, be the two given sides, andX the angle included by them. 1. Construct an angle equal to the angle x (ProblemVI); make one of the legs equal to the side AB, and theother to the side AC. 2. Join BC ; the triangle ABC is the one required. The demonstration follows from Query 1,…
