The figure shows a parallelogram. Find
- ∠h
- ∠g
- ∠f
(a)
∠JNK
= 180° - 38° - 79°
= 63° (Angles sum of triangle)
∠h = ∠JNK = 63° (Vertically opposite angles)
(b)
∠g = ∠JIK = 50° (Alternate angles)
(c)
∠KNJ = ∠h = 63° (Vertically opposite angles)
∠f
= 63° - 50°
= 13° (Exterior angle of a triangle)
Answer(s): (a) 63°; (b) 50°; (c) 13°
