    You might notice that: |dw:1352640138841:dw| A+B=180 and second question, BCA=FDE,so B=F, C=D, A=E, BC=FD, and so on

    @Shadowys so for the first question the answer would be 45? and the second would be BC = DF?

    @Shadowys do you think you help me with this last question? 3. Given the diagram at the right, which of the following must be true? XSF = XTG SXF = GXT FXS = XGT FXS = GXT

    To solve such problems, first label the congruent triangles by their position. FXS=TXG because of the position of the sides.

    so FXS = XGT or FXS = GXT?

    No. the positions can be rotated but not interchanged. i.e. FXS=TXG is same as SXF=GXT
