2 constructions Construct a triangle PQR having PQ = 7 cm,  RPQ = 30 º and  PQR = 57 ºTask:  Draw a rough sketch of the triangle. Making a Rough Sketch: R P Q A Triangle given a side and 2 angles A Triangle given a side and 2 angles  Label its vertices. (Select the base as the given side)  Write the length of the given side. 7 cm 57º  Label the given angles. 30º

3 constructions  Construct line PQ = 7 cm long.  At P construct an angle of 30º. PQ  At Q construct an angle of 57º and label the angle.  Label the point of intersection R. R 7 cm 57º A Triangle given a side and 2 angles A Triangle given a side and 2 angles R P Q 7 cm 57º 30º  Label the angle. 30º
