Question

is △wxz≅△yzx? why or why not? yes, they are both right triangles. no, there is only one set of congruent sides. no, the triangles share side xz. yes, they are congruent by sas.

Explanation:

Step1: Identify triangles and right angles

Triangles WXZ and YZX; right angles at X and Z respectively.

Step2: Check corresponding sides

WX=21cm, YZ=21cm (legs); shared side XZ=ZX (common leg).

Step3: Apply SAS congruence

Included right angles (90°) equal; two sides & included angle congruent.

Answer:

Yes, they are congruent by SAS.
