Question

9 If OA, OB, OC and OD are rays in the anti-clockwise
direction such that
ZAOB = ZCOD = 100°, ZBOC = 82° and ZAOD = 78°.
Is it true to say that AOC and BOD are lines?​

Answer 1

Answer:

no AOC and BOD are lines since AOC =AOB +BOC =182 not 180 and angle BID=BOC+COD =182 not 180

Answer 2

Answer:

AOC is not a line, because ∠ AOB + ∠ COB = 100° + 82° = 182°, which is not equal to 180°. Similarly, BOD is also not a line.
