Side 24 - THEOREM. In the same circle, or in equal circles, equal arcs are subtended by equal chords ; and, conversely, equal chords subtend equal arcs.
Side 22 - CIRCLE is a plane figure bounded by a curved line, all the points of which are equally distant from a point within called the centre; as the figure ADB E.
Side 62 - Similar triangles are to each other as the squares of their homologous sides.
Side 211 - If two angles of one triangle are equal to two angles of another triangle, the third angles are equal, and the triangles are mutually equiangular.
Side 187 - Similar cylinders are to each other as the cubes of their altitudes, or as the cubes of the diameters of their bases.
