A parallelogram.
A trapezium has four points. If it has five, it is not a trapezium unless three of the points are on the same line. And in that case, one of those points is redundant.
parallelogram
Infinitely many points are contained within a non-degenerate quadrilateral.
Yes because it has 4 sides and points. Any shape with 4 sides or points is a quadrilateral.
A polygon...
It is a question of definition. In general language the word quadrilateral has different meanings. In general it is good to discern 3 options: 1. a figure consisting of 4 points is often called (complete) quadrangle, 2. a figure consisting of 4 lines is often called (complete) quadrilateral, 3. a figure consisting of 4 points consecutively and cyclically connected by 4 lines is best called tetragon or quadrigon.
No it isn't because it doesn't have any points.
From 8 non-collinear points, any two points can be connected to form a straight line. The number of lines that can be formed is given by the combination formula ( \binom{n}{2} ), where ( n ) is the number of points. For 8 points, this is calculated as ( \binom{8}{2} = \frac{8 \times 7}{2} = 28 ). Therefore, 28 straight lines can be formed from 8 non-collinear points.
Lines are two connected points with length but no width. When the end points of lines are all shared by other lines a shape is formed. This shape is known as a polygon.
Take the 4 corners (vertices) of any 4-sided figure (quadrilateral). Draw the quadrilateral and its diagonals.
To make a quadrilateral shape, start by defining four points in a two-dimensional space. Connect these points with straight lines to form the four sides of the quadrilateral. Ensure that the points are not all on the same line to maintain a closed figure. You can create various types of quadrilaterals, such as squares, rectangles, and trapezoids, by adjusting the lengths and angles of the sides.
Take any two points on its perimeter. Join them together and, if required, cut along that line. You now have non-regular quadrilateral that is divided.Take any two points on its perimeter.
