Question

which congruence theorem can be used to prove △wxs ≅ △yzs? hl sss asa sas

Explanation:

Step1: Analyze the triangles

$\triangle WXS$ and $\triangle YZS$ are right - angled triangles (given the right angles at $X$ and $Z$).

Step2: Check the hypotenuse and leg

The hypotenuse $WS = YS$ (common side). The leg $XS = ZS$ (marked as equal).

Answer:

HL (Hypotenuse - Leg) congruence theorem.
