1. given: bj≅ cf

which additional statement could you use to prove that ∆bjk ≅ ∆cfh by the hl theorem?

a) jk≅ fh

b) ∠b ≅ ∠c

c) ∠bjk ≅ ∠cfh

d) aj≅ a f

RHL theorem States that if, in a right angled triangle , Hypotenuse and one side of a triangle is equal to hypotenuse and other side , then the two Right triangles  are congruent.

Assuming that ∆B J K, ∆ CF H are two right triangles, considered for Congruency.

If,  BJ≅ CF → [Given]

then, we must find other side ,which are congruent.

So, J K ≅ F H

If , B J and C F are hypotenuse , then JK and F H are two other sides of right triangle, and if  K J and H F are hypotenuse , then JB and F C are two other sides.

Option A:  JK≅ FH

the answer is 175.4379
