Here,   C  E is the external angle bisector of   ∠  A  C  DAnd   C  F is the internal one  C  E can also be called the angle bisector of   ∠  B  C  D

When two lines cross, two angles are created: generally, one acute angle (  &amp;lt;      90    ∘  ) and one obtuse angle. Each of these angles may be bisected; so there are two bisectors (which are at right angles to each other). The description of which one is &quot;internal&quot; and which &quot;external&quot; depends entirely on which side of the intersection—that is, between which two neighbouring rays—you are viewing it from. The bisector coming towards you, or its continuation in the opposite direction, is the internal bisector.
