A) \[\Delta \text{ }DEF\] can be constructed.
B) \[\Delta \text{ }DEF\] is an obtuse angled triangle.
C) \[\Delta \text{ le}\] cannot be constructed
D) \[\Delta \text{ }DEF\] is an acute angled triangle.
Correct Answer: C
Solution :
(c): \[\Delta \,le\] cannot be constructed as sum of only two Ales \[\angle E\] & \[\angle F>180{}^\circ \] \[(\angle E+\angle F=182{}^\circ ),\]which is not possible in a \[\Delta \,le\].You need to login to perform this action.
