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 = 86° (Alternate angles)
∠KLJ
= 86° - 56°
= 30°
(b)
∠KJL
= 180° - 93° - 30°
= 57° (Angles sum of triangle)
∠HJM = 57° (Vertically opposite angles)
∠ JHM
= 180° - 86° - 57°
= 37° (Angles sum of triangle)
Answer(s): (a) 30°; (b) 37°
