Show that triangle BCD is an isosceles triangle on math watch angles in a triangle let me know asap

Determine the relationship of ab and cd given the following points

Given: hf || jk; hg ? jg prove: fhg ? kjg to prove that the triangles are congruent by asa, which statement and reason could be used as part of the proof? fgh ? kgj because vertical angles are congruent. jkg ? hfg because vertical angles are congruent. fhg ? jkg because right angles are congruent. hfg ? kjg because alternate interior angles are congruent.

Don't know how to find x given these segment lengths
