I don't see a question.
OpenStudy (anonymous):
@Directrix just equal segments & angles
Directrix (directrix):
Oh, okay. Let me look again.
Directrix (directrix):
Why are these angles equal in measure: m<ABC = m<DEB
OpenStudy (anonymous):
<ABC = <DEB, EB=ED, AE=CE.. anything else ? :)

because they're vertical angles
Directrix (directrix):
Good.
I'm seeing EA = EC, ED = EB because of tangents drawn to a circle from an external point.
I see two pairs of vertical angles. You found one pair. What is the other pair? @stupidinmath
OpenStudy (anonymous):
oh, <CEB = <AED?
Directrix (directrix):
Yes.
OpenStudy (anonymous):
should I include AB=CD?

I hadn't thought about that. It is true that those are equal so include them.
OpenStudy (anonymous):
Oh, alright.
thank youuuuu c:
Directrix (directrix):
I could draw segment DP and then draw segment BP and then say that they are equal in length because radii of the same circle are congruent.
I assume we are to stick to the segments and angles that are shown on the diagram.
