Geo Arc Measures Math 2

◡ An ARC of a circle is part of the CIRCUMFERENCE The ARC of a circle has the same angle measure as the central angle that forms it. 120 ∘ central angle ? arc ? Drag the words to the ? MQ and NR are diameters. Find the indicated measure. (arc MN has the same measure as angle MON) N M 82 P O 63 Q arc MN = R ∘ MQ and NR are diameters. Find the indicated measure. arc QR N M 82 P ∘ O 63 Q R MQ and NR are diameters. Find the indicated measure. N M 82 P O 63 Q arc PQ = R ∘ MQ and NR are diameters. Find the indicated measure. arc NQ N M 82 ∘ P O 63 Q R MQ and NR are diameters. Find the indicated measure. arc NQR N M 82 P ∘ O 63 Q R MQ and NR are diameters.
