The figure shows a parallelogram. Find
- ∠h
- ∠g
- ∠f
(a)
∠JNK
= 180° - 38° - 65°
= 77° (Angles sum of triangle)
∠h = ∠JNK = 77° (Vertically opposite angles)
(b)
∠g = ∠JIK = 61° (Alternate angles)
(c)
∠KNJ = ∠h = 77° (Vertically opposite angles)
∠f
= 77° - 61°
= 16° (Exterior angle of a triangle)
Answer(s): (a) 77°; (b) 61°; (c) 16°
