Question

Instructions: State what additional information is required in order

to know that the triangles are congruent for the given reason.
Given: SAS
T
Problem 3
=40
V
UV
X
H
W

Answer 1

∠T≅∠W

Explanation:

You want to know what additional information is needed for ∆TUV to be shown congruent to ∆WVX by the SAS postulate, given that UT≅VW and VT≅XW.

SAS

The SAS congruence postulate requires that adjacent sides and the angle between them are congruent to the corresponding sides and angle of the other triangle. The angle between the marked sides is ∠T in ∆TUV, and ∠W in ∆WVX.

You need to know ∠T≅∠W.
