begin mathsize 16px style According space to space the space question comma
In space increment AOD space and space increment COD comma
AD equals CD space space space space space space space space space space space space space space space space space space space space space space space space space space space space space Property space of space kite space shape
angle ADO equals angle CDO space space space space space space space space space space space space space space space increment ABD approximately equal to increment CBD space space by space SSS space straight c. straight p. straight c. straight t
OD equals OD space space space space space space space space space space space space space space space space space space space space space space space space space space space space space Common space side
increment AOD space approximately equal to space increment COD space space space space space space space space space space space space space SAS
angle AOD equals angle COD space space space space space space space space space space space space space space straight c. straight p. straight c. straight t
angle AOD plus angle COD equals 180 degree space
angle AOD plus angle AOD equals 180 degree space
2 angle AOD equals 180 degree
angle AOD equals 90 degree
angle COD equals 90 degree
end style
