Question

In parallelogram DEFG if m_DEF=120 find mZEFG. E 120° .70 D G Answer:

Answer 1

For a parallelogram, the sum consecutive angles are equal to 180 degrees.

Given: mTherefore,

$\begin{gathered} m<\text{DEF}+m<\text{EFG}=180^{\circ} \\ 120^{\circ}+m<\text{EFG}=180^{\circ} \\ m<\text{EFG}=180^{\circ}-120^{\circ} \\ m<\text{EFG}=60^{\circ} \\ x^{\circ}=60^{\circ} \end{gathered}$

Hence, m.
