quadrilaterals

1. QUADRILATERAL AND ITS TYPES

2. QUADRILATERALS A quadrilateral is a polygon with four sides. The origin of the word "quadrilateral" is the two Latin words quadri , a variant of four, and latus , meaning "side". Simple quadrilaterals are either convex or concave . The interior angles of a simple quadrilateral ABCD add up to 360 degrees that is A + B + C + D = 360 degrees.

3. CONCAVE QUDRILATERALS CONCAVE QUDRILATERALS ARE THE QUDRILATERALS WHICH HAVE ATLEAST ONE ANGLE ABOVE THAN 180 DEGREE.

4. CONVEX POLYGON CONVEX QUADRILATERALS ARE THE QUADRILATERALS WICH HAVE ALL THE ANGLES BELOW 180 DEGREE.

5. TYPES OF QUDRILATERALS SQUARE RECTANGLE RHOMBUS PARALLELOGRAM KITE

6. SQUARE A QUAD WITH ALL EQUAL SIDE. ALL ANGLES ARE 90 DEGREE. ALL SIDES ARE EQUAL AND PARALLEL. DIAGONALS ARE EQUAL AND PERPENDICILAR.

7. RECTANGLE OPPOSITE SIDES ARE EQUAL AND PARALLEL. EACH ANGLE IS A RIGHT ANGLE. DIAGONALS ARE EQUAL.

8. RHOMBUS OPPOSITE SIDESE ARE EQUAL AND PARALLEL. ALL ANGLES ARE EQUAL. DIAGONALS ARE EQUAL AND PERPENDICULAR.

9. PARALLELOGRAM OPPOSITE SIDES ARE EQUAL AND PARALLEL. OPPOSITE ANGLES ARE EQUAL. DIAGONALS BISECT EACH OTHER AND ARE UNEQUAL. SUM OF ADDJECENT ANGLES IS 180 DEGREE.

10. KITE ADJECENT SIDES ARE EQUAL. DIAGONALS ARE PERPENDICULAR AND BISECT EACH OTHER. ONE PAIR OFOPPOSITE SIDES IS EQUAL AND ANOTHER IS UNEQUAL.
