ABCD is a parallelogram. ADE and BFE are straight lines. Find the values of
- ∠h
- ∠k
- ∠j
- ∠i
(a)
∠h
= 180° - 51° - 59°
= 70° (Interior angles)
(b)
∠FAB = ∠FBA = 51° (Isosceles triangle)
∠k
= 180° - 59° - 51° - 51°
= 19° (Interior angles)
(c)
∠j
= 180° - 51° - 51°
= 78° (Isosceles triangle)
(d)
∠i = 59° (Alternate angles)
Answer(s): (a) 70°; (b) 19°; (c) 78°; (d) 59°
