In the figure below, WU ≅ VT.
galben [10]

The <u>congruency theorem</u> gives you an opportunity to prove that <u>two triangles</u> are <u>congruent</u>.

Consider triangles WUT and VTU. In these triangles:

  • WU≅VT (given);
  • ∠T≅∠U, m∠T=m∠U=90° (from the diagram);
  • side TU is common.

Note that triangles WUT and VTU are right triangles, because m∠T=m∠U=90°. Side TU is common leg and sides WU and VT are hypotenuses.

HL theorem states: if the hypotenuse (WU) and one leg  (TU) of a right triangle (ΔWUT) are congruent to the hypotenuse (VT) and one leg (TU) of another right triangle (ΔVTU), then the triangles are congruent.

Answer: correct choice is B
