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

condor34 · Answer

The Theorem AAS, meaning angle angle side

jim_thompson5910 · Answer

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

condor34 · Answer

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

Oh mah guh....i dont get this lesson at all..

jim_thompson5910 · Answer

@ANA789 do you see how AAS is used?

jim_thompson5910 · Answer

you have 2 pairs of angles and a pair of sides
