Quadrilateral

1. QUADRILATERAL

3. WHAT IS A QUADRILATRAL
A PLANE FIGURE FORMED BY JOINING FOUR
NON COLLINEAR POINTS IN AN ORDER IS
CALLED A QUADRILATRAL.

4. Vertices : A,B,C and D
Diagonals : AC and BD
Opposite sides : AB and DC ,AD and BC
Adjacent sides : AB and BC,BC and CD, CD and DA, DA and AB
Opposite Angles : A and C , B and D
Consecutive Angles : A and B, B and C, C and D, D and A

5. ANGLE SUM PROPERTY OF QUADRILATRAL
USING SUM ANGLE PROPERTY IN ΔABC AND
ΔADC AND ON ADDING THEM WE GET SUM
360°. SO, WE CAN SAY THAT SUM OF
INTERIOR ANGLES OF A QUADRILATERAL IS
360°

7. PARALLELOGRAM
*OPPOSITE SIDES ARE EQUAL
*OPPOISTE ANGLES ARE EQUAL
* DIAGONALS BISECT EACH OTHER

9. SQUARE
*OPPOSITE SIDES ARE PARALLEL
*ALL SIDES ARE EQUAL
*EACH ANGLE IS OF 90°
*DIAGONALS ARE EQUAL AND
PERPENDICULAR BISECT EACH OTHER

11. TRAPEZIUM
A QUADRILATERAL IN WHICH ONE
PAIR OF OPPOSITE SIDE IS PARALLEL

12. A QUADRILATERAL IN WHICH BOTH
PAIRS OF CONSECUTIVE SIDES ARE
EQUAL
KITE

14. SUMMARY
*A QUADRILATERAL IS A FOUR SIDED POLYGON.
*THE SUM OF ANGLES OF A QUADRILATERAL IS
360°
*THERE ARE MAINLY 6 TYPES OF QUADRILATERAL
. 1. TRAPEZIUM
2. PARALLELOGRAM
3. RECTANGLE
4. SQUARE
5. RHOMBUS
6. KITE
