PSLE In the figure, DEFG is a rectangle. The points J, K, and L lie on the rectangle DEFG. GHJ and LHK are straight lines.
- Find ∠JKH.
- Find ∠HGL.
(a)
∠EKL = ∠GLK = 86° (Alternate angles)
∠JKH
= 86° - 54°
= 32°
(b)
∠JHK
= 180° - 92° - 32°
= 56° (Angles sum of triangle)
∠GHL = 56° (Vertically opposite angles)
∠ HGL
= 180° - 86° - 56°
= 38° (Angles sum of triangle)
Answer(s): (a) 32°; (b) 38°
