We are now going, by accurate constructions, try to find out what is the minimum information needed to have congruent triangles. Each time use only the information provided. You will now determine what sets of measurements will give only one possible triangle. Use a ruler, compass and protractor to construct the following triangles. Question 1: Minimum dimensions are given each time: 1.1 If three sides are given: side, side, side (S,S,S): (4) ΔDEF with DE = 7 cm, DF = 6 cm and EF = 5 cm. 1.2 If three angels are given: angle, angle, angle (: (4) ΔABC with = 80°, = 60° and = 40°.
