In the figure, DEFG and EJKL are two rhombuses. If ∠JKL = 110° and ∠DGF = 91°, calculate
- ∠KJL
- ∠KFE
- ∠LMF
(a)
∠KJL
= (180° - 110°) ÷ 2
= 35° (Isosceles triangle)
(b)
∠KFE = ∠DGF = 91° (Corresponding angles)
(c)
∠LMF
= 91° - 35°
= 56° (Exterior angle of a triangle)
Answer(s): (a) 35°; (b) 91°; (c) 56°
