The presentation is developed by my students .The project is "Kite,special member of Quadrilaterals, The students learnt kite making,kite flying also.They enjoyed Mathematics lesson

1. Kite , special
member of
Quadrilateral family

2. Family of Quadrilaterals

4. A quadrilateral is a four
sided polygon. Therefore
the total number of
degrees of interior angles
is 360°

5. A trapezoid is a quadrilateral with
one pair of parallel lines.

6. A parallelogram is quadrilateral comprised of
two pairs of parallel lines.

7. A rectangle is a parallelogram with four right angles. A
rectangle is a parallelogram, its opposite sides must
be congruent and it must satisfy all other properties
of parallelograms .

8. A rhombus is a type of parallelogram, and what distinguishes its
shape is that all four of its sides are congruent. There are several
formulas for the rhombus that have

10. A rhombus is a type of parallelogram, and what
distinguishes its shape is that all four of its sides
are congruent.
Properties of the rhombus:
1. all four sides are congruent
2. Diagonals bisects each other
3. Diagonals are perpendicular
A square is a rhombus and a rectangle. In other
words, if each angle of a rhombus is 90°, then it's
a square.

11. A square has the properties of a rhombus and a
rectangle. Its sides intersect at 90° and all four
sides are congruent.

12. Kite
Who are you?
Do you belong to family of Quadrilaterals?

13. Kite is a
quadrilateral:
*
has two pairs of sides.
* each pair is adjacent sides
(they meet) that are equal
in length.
Also, the angles are equal
where the pairs meet.
Diagonals meet at a right
angle, and one of the
diagonal bisects (cuts
equally in half) the other.
