GHJK is a parallelogram. GKL and HML are straight lines. Find the values of
- ∠d
- ∠g
- ∠f
- ∠e
(a)
∠d
= 180° - 50° - 57°
= 73° (Interior angles)
(b)
∠MGH = ∠MHG = 50° (Isosceles triangle)
∠g
= 180° - 57° - 50° - 50°
= 23° (Interior angles)
(c)
∠f
= 180° - 50° - 50°
= 80° (Isosceles triangle)
(d)
∠e = 57° (Alternate angles)
Answer(s): (a) 73°; (b) 23°; (c) 80°; (d) 57°
