Quadrilateral math is a parallelogram with diagonals that intersect at point p. /. if you were to prove /, what would be the reason?

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

i believe the answer is the polygon, heptagon.

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.
