Respuesta :
The HL theorem is a special case of the SSS postulate.
Answer:
The HL theorem is special case of side-side-side postulate.
Step-by-step explanation:
We have been given an incomplete sentence and we are supposed to fill in the missing expression for our given sentence.
Sentence:
The hl theorem is a special case of the_______.
We know that Hypotenuse-Leg theorem of right triangles states that if one leg and hypotenuse of any triangle is equal to one leg and hypotenuse of another triangle, then both triangles are congruent.
By corresponding parts of congruent triangles are congruent the third side of 1st triangle will be congruent to third side of 2nd triangle, so, the both triangles are congruent by S-S-S postulate.
Therefore, the missing expression for our given statement is and side-side-side postulate.
