Question

δven ≅ δ____ by ____

Explanation:

Step1: Identify the equal sides

From the figure, we know that \(VO = VE\) (marked as equal), \(VN = VN\) (common side), and \(ON = EN\) (marked as equal).

Step2: Apply the congruence criterion

Since all three pairs of corresponding sides are equal, by the Side - Side - Side (\(SSS\)) congruence criterion, \(\triangle VEN\cong\triangle VON\).

Answer:

$\triangle VON$; $SSS$
