Question

On a graph draw a quadrilateral whose vertices are (1,1), (2,4), (8,4) and (10,1). Justify the quadrilateral.

Answer 1

Given :  quadrilateral  vertices are (1,1), (2,4), (8,4) and (10,1).

To find : Draw quadrilateral  and find type of Quadrilateral

Solution:

quadrilateral whose vertices are (1,1), (2,4), (8,4) and (10,1).

Given Quadrilateral is a trapezium

Slope of line between  (2,4) (8,4)   & Length =  6

= (4 - 4)/(8 - 2)

= 0/6

= 0

Slope of line between (10,1). & (1,1),  & Length =  9

= ( 1 - 1)/(10 - 1)

= 0/9

= 0

Hence Two unequal  Sides are parallel

Quadrilateral is a trapezium
