PSLE In the figure, BCDE is a rectangle. The points G, H, and J lie on the rectangle BCDE. EFG and JFH are straight lines.
- Find ∠GHF.
- Find ∠FEJ.
(a)
∠CHJ = ∠EJH = 88° (Alternate angles)
∠GHF
= 88° - 54°
= 34°
(b)
∠GFH
= 180° - 93° - 34°
= 53° (Angles sum of triangle)
∠EFJ = 53° (Vertically opposite angles)
∠ FEJ
= 180° - 88° - 53°
= 39° (Angles sum of triangle)
Answer(s): (a) 34°; (b) 39°
