Mark any four points A, B, C and D. Join them to make a quadrilateral. Name it.

Name any four Pollutants

Take four points A, B, C and D such that A B, C lie on the same line and D is not on it. Can the four line segments overline AB , overline BC , overline CD , and overline AD from a quadrilateral? Give reason.

Name the points marked in the figure. i) The points in the interior of Quadrilateral. ii) The points on the boundary of Quadrilateral, iii) The points in the exterior of the Quadrilateral.

If A,B,C,D are the angles of a quadrilateral then tan""((A+B)/(4))=

If A,B,C,D are the angles of a cyclic quadrilateral then sinA+sinB=

The area of any cyclic quadrilateral ABCD is given by A^(2)=(s-a)(s-b)(s-c) (s-d) , where 28 = a + b + c + d, a, b,c and d are the sides of the quadrilateral. Now consier a cyclic quadrilateral ABCD of area 1sq.unit and answer the following questions: The minimum perimeter of the quadrilateral is

Plot the points (2,3), (6,3) and (4,7) in a graphsheet. Join them to make it a triangle. Find the area of the triangle.

The area of any cyclic quadrilateral ABCD is given by A^(2)=(s-a)(s-b)(s-c) (s-d) , where 28 = a + b + c + d, a, b,c and d are the sides of the quadrilateral. Now consier a cyclic quadrilateral ABCD of area 1sq.unit and answer the following questions: When the perimeter is minimum, the quadrilateral is necessarily
