PSLE In the figure, EFGH is a rectangle. The points K, L, and M lie on the rectangle EFGH. HJK and MJL are straight lines.
- Find ∠KLJ.
- Find ∠JHM.
(a)
∠FLM = ∠HML = 85° (Alternate angles)
∠KLJ
= 85° - 53°
= 32°
(b)
∠KJL
= 180° - 94° - 32°
= 54° (Angles sum of triangle)
∠HJM = 54° (Vertically opposite angles)
∠ JHM
= 180° - 85° - 54°
= 41° (Angles sum of triangle)
Answer(s): (a) 32°; (b) 41°
