Line C D intersects line A B at point P. What is true about angle ∠APD? It is to angle Angle A P C. It is ✔ vertical to angle Angle C P B.

The statement is saying that line CD intersects line AB at point P. This creates several angles at point P.

The first part of the statement is incomplete, it says "It is to angle Angle APC." but does not provide a relationship. This could be saying that angle APD is equal to, supplementary to, or complementary to angle APC. Without this information, we cannot determine the relationship between angle APD and angle APC.

The second part of the statement says that angle APD is vertical to angle CPB. In geometry, vertical angles are the angles opposite each other when two lines intersect. They are always equal. So, if angle APD is vertical to angle CPB, that means angle APD is equal to angle CPB.
