    In this chapter, we will appearance how to archetype an bend angle ABC to additional bend angle CDE .

    The architecture is based on [http://aleph0.clarku.edu/~djoyce/java/elements/bookI/propI23.htmlBook I, hypothesis 23].

    # amid A and B ang get riangle ABC .

    # riangle ABC and get riangle CDE

    The angles angle ABC and angle CDE are equal.

    # The triangles riangle ABC and get riangle CDE congruence.

    # Accordingly the angles of the triangles equal.

    # Hence, angle ABC and angle CDE are equal.

    Note that any two credibility on the application can be acclimated to make a triangle.
