B. Line m is the perpendicular bisector of AA′¯¯¯¯¯¯¯¯.
C. Line m is parallel to AA′¯¯¯¯¯¯¯¯.
D. A = A′

i dont know

step-by-step explanation:

umm. i dont know

this is a good question! i'll do some research and come back when i have the answer!

804.75

step-by-step explanation:

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
