The missing reason in step 4 is the Base Angles Theorem

What is a Trapezoid?

This refers to a quadrilateral that does not have any parallel sides.

hence, we can see that from the different theorems given, the shape JKLM is an isosceles trapezoid, and to prove that KM ≅ JL, it would be important to check the definition of an isosceles trapezoid, check the reflexive property, and then use the Base Angles Theorem.
