2 constructions A Triangle given 2 sides and an angle A Triangle given 2 sides and an angle

3 constructions Construct a triangle FGH having FG = 7.3 cm,  FGH= 38 º and GH = 4.5 cmTask:  Draw a rough sketch of the triangle. Making a Rough Sketch: H F G A Triangle given 2 sides and an angle A Triangle given 2 sides and an angle  Label its vertices. (Select one of the given sides as a base)  Write the length of the given sides. 7.3 cm 38º  Label the given angle. 4.5 cm

4 constructions 4.5 cm  Construct line FG = 7.3 cm long.  At G construct and label an angle of 38º. FG  Label the point of intersection H.  Write the length of side GH. H 7.3 cm 38º H F G 38º 4.5 cm  Centre G draw an arc radius 4.5 cm.  Join FH. A Triangle given 2 sides and an angle A Triangle given 2 sides and an angle

5 constructions 4.5 cm  Construct line FG = 7.3 cm long.  At G construct and label an angle of 38º. FG  Label the point of intersection H.  Write the length of side GH. H 7.3 cm 38º H F G 38º 4.5 cm  Centre G draw an arc radius 4.5 cm.  Join FH. A Triangle given 2 sides and an angle A Triangle given 2 sides and an angle RESTART END SHOW
