Identify angle relationships for the first blank
Using the Linear Pair knowledge point, we observe that \(\angle APD\) and \(\angle DPB\) form a straight line along line \(AB\).
Therefore, their measures sum to \(180^\circ\):
\[
m\angle APD + m\angle DPB = m + n = 180
\]
Identify relationship between \(\angle APD\) and \(\angle CPB\)
Using the Vertical Angles knowledge point, we observe that line \(AB\) and line \(CD\) intersect at point \(P\).
The angles \(\angle APD\) and \(\angle CPB\) are opposite each other at this intersection.
Thus, they are vertical angles, which means their measures are equal.
Identify relationship between \(\angle EDP\) and \(\angle CPB\)
We observe that line \(ED\) is parallel to line \(AB\).
Line \(CD\) acts as a transversal intersecting both parallel lines.
The angles \(\angle EDP\) and \(\angle CPB\) lie on opposite sides of the transversal and between the parallel lines, making them alternate interior angles.
