3. 3. Definitions Of Quadrialterals  Parallelograms:- a four-sided plane rectilinear figure with opposite sides parallel. Rhombus:- a quadrilateral all of whose sides have the same length. Rectangle:- a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.
4. 4. Definitions Of Quadrialterals  Square:- a plane figure with four equal straight sides and four right angles. Kite:- a kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other. In contrast, a parallelogram also has two pairs of equal-length sides, but they are opposite each other rather than adjacent.
5. 5. Definitions Of Quadrialterals  Trapezium:- a quadrilateral with one pair of sides parallel. Isosceles Trapezium:- an isosceles trapezoid (isosceles trapezium in British English) is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides, making it automatically a trapezoid.

8. 8. Properties Of Quadrilaterals(To Be  Covered)  Parallelogram  Rhombus.  Rectangle.  Square.  Kite.  Trapezium.  Isosceles Trapezium.
9. 9. Parallelogram   Opposite sides are congruent (AB = DC).  Opposite angels are congruent (D = B).  Consecutive angles are supplementary (A + D = 180°).  If one angle is right, then all angles are right.  The diagonals of a parallelogram bisect each other.
10. 10. Rhombus   All sides are congruent by definition.  The diagonals bisect the angles.  The diagonals are perpendicular bisectors of each other.  All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite angles are congruent, and consecutive angles are supplementary).
11. 11. Rectangle   All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite sides are congruent, and diagonals bisect each other).  All angles are right angles by definition.  The diagonals are congruent.
12. 12. Square   All the properties of a rhombus apply (the ones that matter here are parallel sides, diagonals are perpendicular bisectors of each other, and diagonals bisect the angles).  All the properties of a rectangle apply (the only one that matters here is diagonals are congruent).  All sides are congruent by definition.  All angles are right angles by definition.
13. 13. Kite   The diagonals of a kite meet at a right angle.  Kites have exactly one pair of opposite angles that are congruent.
14. 14. Trapezium   At least one pair of opposite sides are equal.  Diagonals bisect each other.  At least one pair of opposite angles are equal.
15. 15. Isosceles Trapezium   Opposite sides of an isosceles trapezoid are the same length (congruent).  The angles on either side of the bases are the same size or measure (also congruent).  The diagonals are congruent.
