An abrasive article comprising: a shaped abrasive particle comprising a body having a first height (h1) at a first end of the body defining a corner between an upper surface, a first side surface, and a second side surface, and a second height (h2) at a second end of the body opposite the first e
1. An abrasive article comprising: a shaped abrasive particle comprising a body having a first height (h1) at a first end of the body defining a corner between an upper surface, a first side surface, and a second side surface, and a second height (h2) at a second end of the body opposite the first end defining an edge between the upper surface and a third side surface, wherein the body comprises a normalized height difference defined by the equation [(h1−h2)/(h1/h2)] of at least about 40 microns, wherein h1 is greater than h2;wherein at least a portion of the upper surface has a curvilinear contour; andwherein the body comprises a bottom surface opposite the upper surface and having a substantially planar contour, wherein the bottom surface has a greater surface area relative to the upper surface. 2. The abrasive article of claim 1, wherein the bottom surface comprises a surface area defined as a bottom area (Ab) and the body has a cross-sectional midpoint area (Am) defining an area of a plane perpendicular to the bottom area and extending through a midpoint of the shaped abrasive particle, and wherein the body comprises an area ratio of bottom area to midpoint area (Ab/Am) of not greater than about 6. 3.
