In the figure, KLMN and LQRS are two rhombuses. If ∠QRS = 124° and ∠KNM = 98°, calculate
- ∠RQS
- ∠RML
- ∠STM
(a)
∠RQS
= (180° - 124°) ÷ 2
= 28° (Isosceles triangle)
(b)
∠RML = ∠KNM = 98° (Corresponding angles)
(c)
∠STM
= 98° - 28°
= 70° (Exterior angle of a triangle)
Answer(s): (a) 28°; (b) 98°; (c) 70°
