PSLE In the figure, CDEF is a rectangle. The points H, J, and K lie on the rectangle CDEF. FGH and KGJ are straight lines.
- Find ∠HJG.
- Find ∠GFK.
(a)
∠DJK = ∠FKJ = 88° (Alternate angles)
∠HJG
= 88° - 54°
= 34°
(b)
∠HGJ
= 180° - 93° - 34°
= 53° (Angles sum of triangle)
∠FGK = 53° (Vertically opposite angles)
∠ GFK
= 180° - 88° - 53°
= 39° (Angles sum of triangle)
Answer(s): (a) 34°; (b) 39°
