Question

1. in parallelogram efgh, what is the relationship between angle e and angle f?

( e ^ { circ } = f ^ { circ } )
( e ^ { circ } + f ^ { circ } = 180 ^ { circ } )
( e ^ { circ } - f ^ { circ } = 180 ^ { circ } )

Explanation:

Step1: Recall the property of a parallelogram

In a parallelogram, adjacent angles are supplementary.

Step2: Identify the relationship between \(\angle E\) and \(\angle F\)

\(\angle E = e^{\circ}\) and \(\angle F = f^{\circ}\) are adjacent angles in parallelogram \(EFGH\).
So, \(e^{\circ}+f^{\circ}=180^{\circ}\)

Answer:

\(e^{\circ}+f^{\circ}=180^{\circ}\)
