Show that the points (-3,5),(3,1),(0,3),(-1,-4) are not a quadrilateral
Answers
as (-3 , 5) , (-3 , 5) & ( 0 , 3) are collinear so these points are not a quadrilateral
Step-by-step explanation:
Show that the points (-3,5),(3,1),(0,3),(-1,-4) are not a quadrilateral
Four points will be Quadrilateral if not more than two pints are collinear
A = (-3 , 5)
B = ( 3 , 1)
C = ( 0 , 3)
D = ( - 1 , - 4)
Slope of AB = ( 1 - 5)/(3 -(-3)) = -4/6 = -2/3
Slope of BC = (3 - 1)/(0 - 3) = 2/(-3) = -2/3
Slope of AB = Slope of BC
=> points A , B & C are collinear
=> (-3 , 5) , (-3 , 5) & ( 0 , 3) are collinear
hence these points are not a quadrilateral
