Angle A also measures 50^o and the side proportional to DF is AW.

Explanation:

Similar triangles have equal angles and proportional sides. In a similar trianglestatement, the order of the vertices indicates corresponding angles and sides.

In this example, triangle DEF is similiar to triangle ACW.

This similarity statement indicates the following:

/_D~=/_Acolor(white)(aaa)/_E~=/_Ccolor(white)(aaa)/_F~=/_W

bar(DE)propbar(AC)color(white)(aaa)bar(EF)propbar(CW)color(white)(aaa)bar(DF)propbar(AW)

So, if m/_D=50^o then m/_A=50^o.

And, side bar(DF)prop side bar(AW)
