The figure shows a parallelogram. Find
- ∠h
- ∠g
- ∠f
(a)
∠JNK
= 180° - 36° - 79°
= 65° (Angles sum of triangle)
∠h = ∠JNK = 65° (Vertically opposite angles)
(b)
∠g = ∠JIK = 51° (Alternate angles)
(c)
∠KNJ = ∠h = 65° (Vertically opposite angles)
∠f
= 65° - 51°
= 14° (Exterior angle of a triangle)
Answer(s): (a) 65°; (b) 51°; (c) 14°
