- In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length. The rhombus is often called a “diamond”, after the diamonds suit in playing cards which resembles the projection of an octahedral diamond, or a lozenge, though the former sometimes refers specifically to a rhombus with a 60° angle (which some authors call a calisson after the French sweet – also see Polyiamond), and the latter sometimes refers specifically to a rhombus with a 45° angle.
- The Lincoln Project (Wikipedia)
The Lincoln Project is an American political action committee (PAC) founded in December 2019 by moderate conservatives and former Republican Party members who oppose U.S. President Donald Trump and Trumpism. During the 2020 presidential election, the organization sought to prevent Trump’s re-election and to defeat Republican candidates who supported him. In April 2020, they endorsed Democratic nominee Joe Biden. From 2022 to 2024, their efforts shifted to thwarting Trump’s re-election bid in the 2024 presidential election, endorsing Democratic nominee Kamala Harris. Following Trump’s victory, the Lincoln Project has focused on criticizing the actions of Trump’s second presidency.
