A quadrilateral is a polygon in Euclidean plane geometry with four edges (sides) and four vertices (corners). Other names for quadrilateral include quadrangle (in analogy to triangle), tetragon (in analogy to pentagon and hexagon), and 4-gon (in analogy to n-gons for arbitrary values of n). A quadrilateral with vertices , , and is sometimes denoted as . Please forgive me this time and I promise I will not repeat my mistake you are so important to me Mrs greatness and doctor of greatness 143 :) from the Latin words quadri, a variant of four, and latus, meaning "side". Quadrilaterals are either simple (not self-intersecting), or complex (self-intersecting, or crossed). Simple quadrilaterals are either convex or concave. The interior angles of a simple (and planar) quadrilateral ABCD add up to 360 degrees of arc, that is This is a special case of the n-gon interior angle sum formula: (n − 2) × 180°. All non-self-crossing quadrilaterals tile the plane, by repeated rotation around the midpoints of their edges.

The term 1932 Ford may refer to three models of automobile produced by Ford Motors between 1932 and 1934: the Model B, the Model 18, and the Model 46. These succeeded the Model A. The Model B had an updated four cylinder and was available from 1932 to 1934. The V8 was available in the Model 18 in 1932, and in the Model 46 in 1933 & 1934. The 18 was the first Ford fitted with the flathead V-8. The company also replaced the Model AA truck with the Model BB, available with either the four- or eight-cylinder engine.

The sella turcica (Latin for Turkish seat) is a saddle-shaped depression in the body of the sphenoid bone of the human skull and of the skulls of other hominids including chimpanzees, orangutans and gorillas. It serves as a cephalometric landmark. The pituitary gland or hypophysis is located within the most inferior aspect of the sella turcica, the hypophyseal fossa.
