In the figure, JKLM and KPQR are two rhombuses. If ∠PQR = 106° and ∠JML = 97°, calculate
- ∠QPR
- ∠QLK
- ∠RSL
(a)
∠QPR
= (180° - 106°) ÷ 2
= 37° (Isosceles triangle)
(b)
∠QLK = ∠JML = 97° (Corresponding angles)
(c)
∠RSL
= 97° - 37°
= 60° (Exterior angle of a triangle)
Answer(s): (a) 37°; (b) 97°; (c) 60°
