Question

Which one of the following triangles can be constructed? *

∆ABC in which AB=7 cm , ∠ A=100, ∠ B=90°
∆DEF in which DF=8cm, ∠E=90°, ∠D=50°
∆XYZ in which ZX=4.5 cm, ∠X=150, ∠Z=40°
∆PQR in which QR=1.8 cm, ∠P=110°,∠R=90°​

Answer 1

Step-by-step explanation:

i) Draw EF=4㎝

ii) From E draw a line right angled to EF

iii) From F, taking 5㎝ as radius cut an arc.

iv) Point of intersection of perpendicular line and the arc is point D

v) Join DE and EF.
