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 = 83° (Alternate angles)
∠JKH
= 83° - 54°
= 29°
(b)
∠JHK
= 180° - 94° - 29°
= 57° (Angles sum of triangle)
∠GHL = 57° (Vertically opposite angles)
∠ HGL
= 180° - 83° - 57°
= 40° (Angles sum of triangle)
Answer(s): (a) 29°; (b) 40°
