Observe the figure clearly.
To Prove: KA = KC
Proof:
Consider the triangles 
KB = KB (Common side)
(each angle is of 90 degree)
(As BY bisects angle ABC)
Therefore, 
By AAS congruence Theorem which states:
"If two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent".
Hence, the given triangles are congruent by AAS congruence criteria.
