    Hint: angle HIG = angle FIE because they are vertical angles. Vertical angles are always congruent

    I just dont get what all those postulates are. They were explained, but i failed at grasping the concept

    another hint: http://www.regentsprep.org/regents/math/geometry/gp4/ltriangles.htm that link shows a list of triangle congruence theorems. You will use exactly one of those theorems

    Basically Theorems and Postulates are just facts that later on in Geometry allow you to solve more complex questions.

    J is the top most point? I can't see it since it's cut off

    JK || PM so that means angle KJN = angle MPN (corresponding angles) |dw:1436487989292:dw|

    KO || NM so, angle KOJ = angle MNJ (corresponding angles) |dw:1436488055576:dw|
