slope of line BC =
Both the pairs of opposite sides of the quadrilateral are parallel
ABCD is a parallelogram​

Answer 1

Answer:

If A(6, 1), B(8, 2), C(9, 4) and D(7,3) are the vertices of ABCD,

show that ABCD is a parallelogram.

Solution If A(6, 1), B(8,2), C(9, 4) and D(7.3) are the vertices of ABCD,

show that ABCD is a parallelogram

Solution

D

Slope of line AB -2-1/8-6=

Slope of line BC =4-2/2-8=

pto

slope of CD =3-4/7-9=

Slope of line DA= 3-1/7-6=

Slope of line AB =

line AB||line CD

slope of line BC =

Both the pairs of opposite sides of the quadrilateral are parallel

ABCD is a parallelogram
