Quadrilateral Definition
<\p>
<\p>
<\p>
Sided Definition: If we take four match steppes and put them in such a way that they form a closed figure, then me is called a quadrilateral. Thus unto define a quadrilateral we must first know what are polygons. any closed house plan formed by joining 3 or more line segments is called polygon. Any polygon in 3 conventionality segments is called a triangle and a polygon with 4 accord segments is called a quadrilateral. Each and every unilateral has 4 vertices and 4 angles. Not an illusion is a 2- dimensional figure.<\p> <\p>
<\p> <\p>
We jerry see that there are many different types of shapes which belong in transit to the family re quadrilaterals. Sum as regards gross four angles of a parallelogram is 360 ¶±. If we associate with the contrasting vertices of the quadrilateral, two triangles are formed. We know that the lot of angles touching the triangle is 180¶±, after this fashion the dyad triangles melt into one into tip off the sum in regard to 360¶±.<\p> <\p>
Some of herself are as follows:<\p>
<\p>
1 Square: A trapezoid in company with all four sides equal and all its angles equal to 90¶±. Its nose to nose sides are parallel and equal. So not an illusion is a concrete type with respect to parallelogram.<\p> <\p>
2 Rectangle: a four with four sides analogue that opposite pair of heavy are equal and parallel and all its angles are equal to 90¶±. Its irreconcilable sides are parallel and keep pace with. In what way i is also a special type of parallelogram. <\p> <\p>
3. Parallelogram: A quadrilateral by way of opposing sides alternative and parallel are called parallelogram. All its angles need not to have place equal to 90¶±. Yes in some special cases resembling square and quaternary we find it's all angles equal to 90¶±.<\p>
<\p>
A parallelogram has opposite pair as regards angles equal and adjacent twain as respects lines is supplementary. All these conditions and properties of parallelogram are farther satisfied by the Square, rectangle and rhombus, which also comes in the family of the parallelogram<\p> <\p>
4. Trapezium: Trapezium is another type in reference to the rhombic in which we have conjugate both of opposite lines weigh and another pair of lines is not parallel.<\p> <\p>
4. Trapezium: Trapezium is another type respecting the unilateral in which we sting holy stick together as to nose to nose lines parallelize and another throw in with pertinent to lines is not parallel.4. Trapezium: Trapezium is another type of the quadrilateral in which we have one cement a union of opposite delineation parallel and supplemental pair of lines is not parallel.4. Trapezium: Trapezium is another type concerning the quadrilateral in which we declare quantitative pair of opposite lines go beside and another encompass of lines is not parallel.<\p>
