phi · Answer

see http://www.mathopenref.com/constparallel.html

phi · Answer

It looks like they constructed a line parallel to the base leg.

anonymous · Answer

So is it the last one? but they are parallel not perpendicular so I dont think it is

anonymous · Answer

The angles are congruent it seems though

phi · Answer

A transversal (the left leg)  through two parallel lines has corresponding angles that are congruent.

phi · Answer

so maybe they are constructing parallel lines as a means to construct congruent angles.

anonymous · Answer

Yes because the angles are congruent I am going to go with that it seems to be the only logical answer thanks
