Firstly, I thank our PRINCIPAL Sir N P Rajan for their co-operation in preparing this project. Then, I thank our Maths teacher Nagaraj N S for assigning us this PPT. I also thank our Computer Sir for their co-operation in this PPT. I thank my classmates and seniors for their help in making this project. I also thank our team-mates for their help in making this project a grand success.INTRODUCTION: What is a quadrilateral? It is a 4-sided polygon, which is made up entirely of line segments. Quadrilaterals can be divided into 5 types i.e.., square, rectangle, rhombus, trapezium, parallelogram. INTRODUCTIONSlide 5: WHAT A QUADRILATERAL ?

They are different shapes, yet they all have 4 sides…QUADRILATERAL : A quadrilateral is a polygon with four sides. A quadrilateral is named by its vertices. QUADRILATERALSQUARE: It is a quadrilateral having all sides equal. All the angles are 90 degrees. The diagonals are equal and bisect each other perpendicularly. The angle-sum property is 360 degrees. SQUAREHow are they different?: How are they different? SQUARE 4 congruent sides 4 congruent angles ( Square = opposite of cool.)RECTANGLE: It is a 4-side polygon having opposite sides equal. Diagonals are equal and bisect each other Angle-sum property is 360 degrees. All the angles are 90 degrees. RECTANGLETrapezium: In this polygon, only one pair of opposite sides are equal. Diagonals are unequal TrapeziumHow are they different?: How are they different? TRAPEZOID Only 1 pair of parallel sides The trapezoid is usually the funkiest looking quadrilateral.PARALLELLOGRAM: It is a 4-sided polygon having opposites sides of equal length. Diagonals are equal and bisect each other. Angle-sum property is 360 degrees. PARALLELLOGRAMHow are they different?: How are they different? PARALLELOGRAM 2 pairs of parallel sides Opposite sides congruent Opposite angles congruentRHOMBUS: It is a 4-sided polygon with all side equal. Diagonals are equal and bisect each other perpendicularly. All sides are 90 degrees. Angle-sum property is 360 degrees. RHOMBUSHow are they different?: How are they different? RHOMBUS A parallelogram with 4 congruent (equal) sidesSlide 18: In figure A, the quadrilateral is named PQRS or QRSP or RSPQ or SPQR. The order of the vertices is important. In figure B, the quadrilateral is named MNOP. In figure C, the quadrilateral is named DEFG. A B C P Q R S M N O P D E F GIn quadrilateral ABCD, the vertices are A, B,C, and D. Vertices A and B, B and C, C and D, D and A are consecutives vertices. Vertices A and C, B and D are opposite vertices. D: In quadrilateral ABCD, the vertices are A, B,C, and D. Vertices A and B, B and C, C and D, D and A are consecutives vertices. Vertices A and C, B and D are opposite vertices. D A B C DTwo sides with common vertex, like AB and BC, are consecutive sides. AB and DC, AD and BC, on the other hand are opposite hand.: Two sides with common vertex, like AB and BC, are consecutive sides. AB and DC, AD and BC, on the other hand are opposite hand. A B C DSlide 21: Two angles with a common side, like <A and <D, are consecutive angles. <A and <C, <B and <D on the other hand are opposite angles.

Switch with a friend and have them label your quadrilaterals and you label theirs.CONCLUSION: Learning Outcome: By seeing this project, we can understand the all aspects/info about quadrilaterals. Identify the quadrilaterals properly and their properties i.e., angle-sum, exterior-angle property etc. CONCLUSIONBIBLIOGRAPHY: We have taken help from the following sources to make this project a grand success: VIII Class Maths Textbook Google search Wikipedia Search on Quadrilaterals www.author stream.com – Downloaded PPT.
