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 = 82° (Alternate angles)
∠FGE
= 82° - 53°
= 29°
(b)
∠FEG
= 180° - 89° - 29°
= 62° (Angles sum of triangle)
∠DEH = 62° (Vertically opposite angles)
∠ EDH
= 180° - 82° - 62°
= 36° (Angles sum of triangle)
Answer(s): (a) 29°; (b) 36°
