Question

previous answer ∠e≅∠t what additional information is needed to prove congruence with sas criteria?

Explanation:

Step1: Recall SAS criteria

SAS (Side - Angle - Side) requires two pairs of congruent sides and the included angle congruent. We know $\angle E\cong\angle T$.

Step2: Identify existing sides

We see that $EF$ and $FG$ are sides of the triangles. We need the sides adjacent to $\angle E$ and $\angle T$ to be congruent.

Step3: Determine needed sides

We need $ET\cong EG$ and $FT\cong FG$. Since we already have information about the angle $\angle E\cong\angle T$, we specifically need $ET = EG$ and $FT=FG$ (or the equivalent side - congruence statements in terms of the triangles' naming).

Answer:

We need $ET\cong EG$ and $FT\cong FG$
