    4th one.. you said ASA the first time and that was incorrect :) first look at the triangle and tell me if it has 2 sides and 1 angle that match or 1 side and 2 angles that match

    Use the diagram below. Tell why each statement is true. ∠A ≅ ∠ C ∠AXB ≅ ∠CXD ∆ABX ≅ ∆CDX

    okay i can try but idk how well this will end LOL. So firstly, we want to state why angle A is CONGRUENT (equal) to angle C. Hint: we are given that \[AB // CD\] , so why would <A = <C ?

    okay, well between two parallel lines: these angles will be EQUAL because they are alternate angles. |dw:1436365370736:dw|

    so if you look at your diagram, what would your reason be for why <A = <C ?

    if lines are paraellel then alt interior angles are congruent?

    Note: when 2 lines CROSS, the angles opposite each other (vertically opposite angles) are equal (congruent)
