Jawab:
AOB = 90°
DOA = 90°
OCB = 45°
OBC = 45°
BOC = 90°
OAD = 45°
ODC = 45°
OCD = 45°
Penjelasan dengan langkah-langkah:
AOB + BOC + COD + DOA = 360°
AOB = BOC = COD = DOA
AOB + AOB + AOB + AOB =360°
4 AOB = 360°
AOB = 90°
AOB = DOA = BOC = 90°
OCB + OCD = 90°
OCD = OCB = CBO = OBA = OAB = OAD = ODC = ODA
OCB + OCB = 90°
2OCB = 45°
OCD = OCB = CBO = OBA = OAB = OAD = ODC = ODA = 45°
