Drawing two tiny parallel lines over the segment will indicate that it is a congruent segment. The little arc symbol can also be drawn over the segment or the angles.

It depends on what is given.In general, one half of the bisected angle is proven to congruent to the other half. By the Definition of an Angle Bisector, the bisected angle can be proven bisected.---- To show that two angles are congruent:One way to prove the two angles congruent is to show that their measures are equal. This can be done if there are numbers on the diagram. Use the Protractor Postulate or the Angle Addition Postulate to find the smaller angles' measures, if they are not directly marked. Then use the Definition of Congruent Angles to prove them congruent.Given that the smaller angles correspond on a congruent or similar pair of figures in that plane and form an angle bisector, the Corresponding Parts of Congruent Figures Postulate or Corresponding Parts of Simlar Figures Postulate may be used.
In a triangle, if two sides show to be congruent, you would use the reflexive property of congruence. (AB=AC) A /\ / \ / \ B C As shown in this diagram AB and AC obviously show to be parallel(as shown by the slash marks...

Once you prove that a diagram is congruent then you can say that all the parts are congruent.
Drawing two tiny parallel lines over the segment will indicate that it is a congruent segment. The little arc symbol can also be drawn over the segment or the angles.
No, the sets and subsets can be any shape, but circles and rectangles are neater. Also, circles or rectangles will usually intersect in only one part whereas very wriggly shapes can have multiple intersections.
