Q.3 Examine whether you can construct ?DEF such that EF = 7.2 cm, m$$\angle$$E = 110° and m$$\angle$$F = 80°. Justify your answer.
To construct $$\triangle$$DEF with the given measurement, is not possible.
$$\therefore m\angle E + m\angle F = 110° + 80°$$
$$\therefore \triangle$$DEF is not possible to construct.
