Introduction :
Polygon with four sides and four vertices or corners is calling as the quadrilateral. Analogy with triangle is used to the term quadrangle, and at times tetragon for constancy with pentagon (5-sided), hexagon (6-sided) and so on. The word quadrilateral is prepared of the expressions quad and lateral. Quadrilaterals are easily and composite is known as crossed. Easy quadrilaterals are also concave or convex.
Quadrilateral Practice:
Repeated rotation approximately the midpoints of their edges of the plane in the every one convex quadrilateral practice tile.
Square:
A square is a standard quadrilateral practice.
Oblong:
An oblong is a quadrilateral whose positions are all right position, but whose sides are all the different length
Parallelogram:
A parallelogram is a quadrilateral practice whose indirection sides are parallel to every other, and whose position may or may not all be the equal length.
Example Problems for Quadrilateral Practice :
Example 1:
Find the area of the square have side-length 50 cm?
Solution:
The area of the Square=L2
Where L=50
Length=L*L
=50*50
=2500
Example 2:
Find the area of the rectangle have a length of 9cm and a width of 13cm?
Solution:
The area of the rectangle = length * width
=9*13
=117
Convex Quadrilaterals – Parallelograms:
Two pairs of the similar sides of quadrilateral is parallelogram. Equal length of the opposite sides contains the equivalent conditions. Square, rhombus, rectangle are contain in the Parallelograms.
Four side polygons is the two dimension of the quadrilateral partice the 360 degree if the whole angle of the quadrilateral. Two is the maximum diagonal quadrilateral and these diagonal of the quadrilateral if the general points. Fore vertices and four corners are including in the quadrilateral.
Equivalent parallelogram is the related with quadrilateral practice. Isoperimetric map is the properties of the quadrilateral, it is most conveniently. The equivalent parallelogram generates a usual means of defining a standard family of quadrilaterals. This definition is used collectively with additional properties to obtain in a moderately easy manner estimates, in suitable seminorms or norm, of the isoperimetric map
