Question 825970: Hi! I need urgent help with my homework please. It's a proofing exercise and thus I would prefer it if the answer was in statement/reason form, eg. Statement (Reason).
Anyways, here is a link to the exercise, and since it had a figure I had to upload it as a picture. http://prntscr.com/2gddg2 (copy and paste this link in your browser or click it if it's a hyperlink).
Please help me a.s.a.p and I'll make sure to thank everyone who helps.

ΔKGJ ∽ ΔIGH                             Two triangles are similar if an angle
                                        of 1 triangle is congruent to the
                                        angle of the other triangle and the 
                                        sides containing these angles are in 
                                        the same ratio. (Like "SAS" but for
                                        similar, not congruent, triangles)

∠1 ≅ ∠3                                corresponding parts of similar 
                                        triangles

∠1 ≅ ∠2                                Given

∠2 ≅ ∠3                                Angles congruent to the same angle  
                                        are congruent
 
EF ∥ HI                                 If the alternate interior angles are 
                                        congruent, then the lines are
                                        parallel.”
