Solution: Steps of construction: (i) Draw QR = 3.5 cm. Step 2: Using a protractor draw an angle of 60° from Point A. Triangle ABC has to be constructed with AB = BC = CA = 5.5 cm. It will even tell you if more than 1 triangle can be created. A Euclidean construction. You've divided the triangle into three equal sections (each of which is a triangle). Next, insert a compass at an end of the line you've just drawn and put a pencil at the other. It works because the compass width is not changed between drawing each side, guaranteeing they are all congruent (same length). Using a protractor measure ∠ACB. Thus, ABC is the required triangle. To form the apex, draw a second arc with the pencil so it crosses over the first arc. An equilateral triangle has 3 congruent sides. An acute triangle has 3 acute angles. Step 1: Draw a straight line 5 cm long. 2. 3. The altitude shown h is hb or, the altitude of b. A. It will even tell you if more than 1 triangle can be created.
