Question

define quardilateral. and write different types of quardilaterals with explanation by figures

Answer 1

All closed, plane figure having 4 sides comes under the category of quadrilateral.

types of quadrilateral are.
1.Squre
2. rectangle
3. rhombus
4. trapezium
5.parallelogram

Answer 2

================================

what is quadrilateral

=>A quadrilateral is a closed figure with four straight sides.it is a four sided figure .

=> in a quadrilateral Each point where two sides touch is called a vertex

there are 7 types of quadrilatrales

let us discuss them 1by1

=>1)

sqaure

=> a square has 4 straight lines where all  4 are congruent

=>the opposite linees anre always parelelel

=>all angles and sides are equal.

=> area = 4 *side

=>perimeter = side *side

2)rectangle 

=>all angles are 90c degrees

=>Opposite sides are parallel and congruent.

=>Area = L * B

Perimeter = 2(L+B)

3) Parallelogram

=>Opposite sides are parallel and congruent

=>the opposite angles are congruent.

=>it is not 90 degrees
d
=>if diagnals are there then it is bisected into 2  triangles

=>Area = L * H

=>Perimeter = 2(L+B)

4)rhombus

=> All sides are congruent.

=>it is not 90 degrees

=>Area = (a* b) / 2

=>Perimeter = 4L

5)trapezium

=>The bases  are parallel to each other

=>nothing is congruent [ sides,angles,diagnols]

=>Area = (1/2) h (L+L2)

=>Perimeter = L + L1 + L2 + L3
