Answer:
1.
2.(a)Therefore , Side LJ =side CA
(b) BC = KL
Step-by-step explanation:
1.
we know that, vertically opposite angles are congruent .
2.
(a)SAS = side,angle , side
Given ,side AB = side KJ
and ∠CAB= ∠LJK
All Pythagorean Triples are unique.
Since side AB = side KJ
Therefore , Side LJ =side CA
It satisfies SAS postulate ThereforeΔABC≅ΔKJL
(b)
HL Theorem: If hypotenuse and one leg of of a right triangle are congruent to the hypotenuse and one leg of of other right triangle , then the triangle congruent.
Since,
All Pythagorean Triples are unique.
Then hypotenuse of ΔABC=ΔLKJ ⇔BC = KL
