A Sector of a Circle
Geometric figure identified as the circular sector abcd, among faint circle constructions
A lightly drawn geometric sheet. The transcribed note identifies the figure a b c d as a sector of a circle, labelled with the points c d and b a. The sheet also carries faint circle constructions with inscribed figures at the right and a ruled scale along the lower edge, together with show-through from the recto; these are not transcribed.
