Answer:
HA:A hypotenuse and an acute angle define congruence
HL:A hypotenuse and a leg define congruence
LL: Two legs define congruence
LA:A leg and an acute angle define congruence
Step-by-step explanation:
HA theorem:
When hypotenuse and one acute angle of a triangle is congruent to hypotenuse and one acute angle of a other triangle, then the triangles are congruent
HL theorem:
When hypotenuse and one leg of a triangle is congruent to hypotenuse and one leg of other triangle, then the triangles are congruent
LL theorem:
When two legs of a triangle is congruent to the two legs of other triangle, then the triangles are congruent
LA theorem:
When one leg and one acute angle of a triangle is congruent to one leg and one acute angle of other triangle, then the triangle are congruent
