Square (geometry) - Definition and Overview |
|
|
In plane geometry, a square is a polygon with four equal sides and equal angles. Those angles are then necessarily right angles. Squares are regular quadrilaterals, rectangles, rhombi, kites, parallelograms, and isosceles trapezoids/isosceles trapezia.
The diagonals of a square are equal and
conversely, if the diagonals of a rhombus are proven
to be equal, then that rhombus must be a square.
The coordinates for the vertices of a square centered at the origin and with side length 2 are (±1, ±1), while the interior of the same consists of all points (x0, x1) with -1 < xi < 1.
