PSLE In the figure, ABCD is a rectangle. The points F, G, and H lie on the rectangle ABCD. DEF and HEG are straight lines.
- Find ∠FGE.
- Find ∠EDH.
(a)
∠BGH = ∠DHG = 83° (Alternate angles)
∠FGE
= 83° - 47°
= 36°
(b)
∠FEG
= 180° - 93° - 36°
= 51° (Angles sum of triangle)
∠DEH = 51° (Vertically opposite angles)
∠ EDH
= 180° - 83° - 51°
= 46° (Angles sum of triangle)
Answer(s): (a) 36°; (b) 46°
