Construct KM, a bisector of the base HJ.
to prove:
in ΔKHM and ΔKJM
bisects [Given]

[Given]
Reflexive property of congruence that any geometric figure is congruent to itself.
[by definition of Reflexive property of congruence]
SSS(Side-Side-Side) Postulates states that if three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent.
therefore, by SSS postulates
ΔKHM ΔKJM
By CPCT [Corresponding Part of congruent Triangle]
proved!
