Question

In $△$ DEF , $\angle$ D = 55° and $\angle$ E = 105°. Which is the correct information needed to construct the triangle?

• A. $\overline{EF}$ =6.5 cm
• B. $\overline{DE}$ =3.5 cm
• C. $\overline{DF}$ =11 cm
• D. $\angle$ F = 20°

Answer 1

The correct option is B $\overline{DE}$ =3.5 cm

Using ASA criteria, We can construct the $△$ DEF as the angles $\angle$ D = 55°, $\angle$ E = 105° and the included side $\overline{DE}$ =3.5 cm are given.
