Question

Students should take examples of their own and practice construction of triangles.

i. In ∆PQR, l(PQ) = 5 cm, l(QR) = 6.8 cm, l(PR) = 5.5 cm. 

ii. In ∆XYZ, l(XY) = 5.7 cm, m∠Y = 120° , l(YZ) = 7 cm. 

iii. In ∆RST, l(ST) = 6.7 cm, m∠S = 60° , m∠T = 40°. 

iv. In ∆UVW, m∠U = 90° , l(UV) = 5 cm, l(VW) = 6 cm.

Answer 1
