NPQR is a rhombus, KLR and PLQ are straight lines. If PL = LR, ∠LRQ = 21° and ∠MPQ = 35°, find
- ∠LQR
- ∠MKL
(a)
∠LQR
= 88° - 21°
= 67° (Exterior angle of a triangle)
(b)
∠PKL
= 88° - 35°
= 53° (Exterior angle of a triangle)
∠MKL
= 180° - 53°
= 127° (Angles on a straight line)
Answer(s): (a) 67°; (b) 127°
