Without measuring, which angle is larger: ∠AOB or ∠BOC?In the figure, ∠AOB = 35° and ∠BOC = 50°. What is ∠AOC?Arms OA and OB cross the protractor scale as shown, and neither is on 0. What is ∠AOB?Meena put arm OA on the 20 mark instead of 0, and OB crossed at 85 on the same scale.…Arm OA is on the left of the base line. Read ∠AOB carefully.
