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 = 83° (Alternate angles)
∠GHF
= 83° - 55°
= 28°
(b)
∠GFH
= 180° - 93° - 28°
= 59° (Angles sum of triangle)
∠EFJ = 59° (Vertically opposite angles)
∠ FEJ
= 180° - 83° - 59°
= 38° (Angles sum of triangle)
Answer(s): (a) 28°; (b) 38°
