In the figure, not drawn to scale, O is the centre of the semi circle and OFGH is a rhombus. ∠OHJ = 31°. Find
- ∠g
- ∠h.
(a)
OH = OJ = Radius
∠HOJ
= 180° - 31° - 31°
= 118° (Isosceles triangle)
∠g = ∠HOJ = 118° (Corresponding angles, FG//OH)
(b)
∠h
= 180° - 118°
= 62° (Interior angles, GH//FO)
Answer(s): (a) 118°; (b) 62°
