... Proof: We can find a rigid motion taking side AB to sideXY, and point C to a point C’ on opposite side of line XY from point Z, as usual. Now reflecting in line XY sends side XC’ up to a segment making the same angle as side XZ, hence C’ goes to a point C’’ lying on the line through XZ. Similarly se ...
