JKLM is a parallelogram. JMN and KPN are straight lines. Find the values of
- ∠g
- ∠j
- ∠i
- ∠h
(a)
∠g
= 180° - 51° - 58°
= 71° (Interior angles)
(b)
∠PJK = ∠PKJ = 51° (Isosceles triangle)
∠j
= 180° - 58° - 51° - 51°
= 20° (Interior angles)
(c)
∠i
= 180° - 51° - 51°
= 78° (Isosceles triangle)
(d)
∠h = 58° (Alternate angles)
Answer(s): (a) 71°; (b) 20°; (c) 78°; (d) 58°
