WebA convex polygon is a polygon where all the interior angles are less than 180º. A polygon in which at least one of the angles is greater than 180° is called a concave polygon. The diagonals of a convex polygon lie inside the polygon. A convex polygon is a polygon where the line joining every two points of it lies completely inside it. WebVocabulary words: diagonal, upper-triangular, lower-triangular, transpose. Essential vocabulary word: determinant. In this section, we define the determinant, and we present one way to compute it. Then we discuss some of the many wonderful properties the determinant enjoys. Subsection 4.1.1 The Definition of the Determinant
A polygon is defined as a flat or plane, two-dimensional closed shapebounded with straight sides. A diagonal is a line segment connecting the opposite vertices (or corners) of a polygon.

Webrectangle. The rhombus has a square as a special case, and is a special case of a kite and parallelogram. 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.
WebA square or rectangle has four corners with right angles. Examples of right angles are all around us. We can see right angles in the corners of a room, book, cube, windows and at several other places. A vertical and a horizontal line makes the most common right angles. However, diagonal lines intersecting each other also form right angles. holby ambulance serviceWebThe diagonals bisect each other. Rhombus. A rhombus has four sides of equal lengths.
