Question

Instructions: State what additional information is required in order to know that the triangles are congruent for the given reason.

Answer 1

To prove that ΔWVU and ΔUBW are congruent by the Side-Side-Side Triangle Congruence Postulate, we need to know that VW is congruent to BU. After having this information given to us, here's what our proof looks like:

VW = BU----------Given

VU = BW----------Given

WU = UW----------They are lengths of the same line segment

ΔWVU = ΔUBW----------Side-Side-Side Triangle Congruence Postulate

Answer 2

WV = SU

Explanation:

We’ve been told that WS = VU and obviously since they share WU that’s equal too, so they need to tell us that WV is equal to SU to show congruency by SSS
