Task 2 : Quadrilaterals
About the presentation
each of national country flag has a different
quadrilateral in its design.
This PowerPoint Presentation shows the following
information for each flag:
• Name of the Country.
• Flag of the Country.
• Name of the quadrilateral(s) in the design of the
flag.
• properties of the quadrilateral(s) in the design of the
flag.
• formula for area of the quadrilateral(s) in the design
of the flag.
United Arab emirates flag
United Arab emirates flag
In this flag there is only one type of quadrilateral shape that is rectangle.
To know that is rectangle both pair of opposite sides are congruent, and the angles are equal to 90
degree.
To find the area of rectangle , multiply length and width (LW).
Denmark flag
Denmark flag
In this flag there is two type of quadrilateral shape that is rectangle and square.
To know that is rectangle both pair of opposite sides are congruent, and the angles are
equal to 90 degree the same for square but also the diagonals are perpendicular and all
sides are congruent.
To find the area of rectangle , multiply length and width (LW) but for square multiply side
and side (SS) .
Kuwait flag
Kuwait flag
In this flag there is three type of quadrilateral shape that is isosceles trapezoid,
trapezoid and rectangle .
To know that is trapezoid leg angels are supplementary but for isosceles trapezoid the
legs are congruent then for the rectangle both pair of opposite sides are congruent,
and the angles are equal to 90 degree.
To find the area of rectangle , multiply length and width (LW) but for trapezoid base
1 plus base 2 times the hight then dived by 2 . H(b1+b2)/2
Sudan flag
Sudan flag
In this flag there is two type of quadrilateral shape that is trapezoid
To know that is trapezoid leg angels are supplementary
To find the area of trapezoid base 1 plus base 2 times the hight then dived by
2 . H(b1+b2)/2
Flag that there design are not quadrilateral
Japan
Brazil
Tunisia
Flag that there design are not quadrilateral
Because there shape is not quadrilateral they have more than one side or no side and
quadrilateral is ONLY 4 sides and 4 angels .
