Affine-regular polygon properties of regular polygons are invariant under affine transformations, and affine-regular polygons share the same properties. For instance, an affine-regular quadrilateral can be equidissected into formula_1 equal-area triangles if and only if formula_1 is even, by affine invariance of equidissection and Monsky's theorem on equidissections of squares. More generally an formula_3-gon with formula_4 may be equidissected into formula_1 equal-area triangles if and only if formula_1 is a multiple of formula_3. Affine-regular polygon In geometry, an affine-regular polygon or affinely regular polygon is a polygon that is related to a regular polygon by an affine transformation. Affine transformations include translations, uniform
All Sides All Sides All Sides is the sixth studio album by O.A.R., which was released on July 15, 2008 by Everfine Records, Lava Records and Atlantic Recording Corporation. Marc Roberge revealed in an interview with Songfacts that "Dinner Last Night" was inspired by an episode of "Seinfeld". The album was generally received negatively among professional reviewers. Rolling Stone attributes the album's failure to a change in the group's style, calling the album "a poor man's Goo Goo Dolls". Allmusic claims, "O.A.R. wasn't designed for Top 40 radio, which makes "All Sides"...disappointing." The album was the band's highest charting prior to the
