The diagonals are AC and BD . show that the diagonals have the same mi

1.	The diagonals are AC and BD . show that the diagonals have the same midpoint
Answer» ANSWER: be P be the mid point of AC by MIDPOINT formula x=2+(-1)/2 x=1/2 y=3+(-2)/2 y=1/2 therefore P(x,y)=(1/2,1/2) be Q be the mid point of BD by midpoint formula x=3+(-2)/2 x=1/2 y=-1+2/2 y=1/2 therefore Q(x,y)=(1/2,1/2) as P=Q therefore we can say that the diagonals have the same mid point

The diagonals are AC and BD . show that the diagonals have the same midpoint

Answer»

be P be the mid point of AC

by MIDPOINT formula

x=2+(-1)/2

x=1/2

y=3+(-2)/2

y=1/2

therefore P(x,y)=(1/2,1/2)

be Q be the mid point of BD

by midpoint formula

x=3+(-2)/2

x=1/2

y=-1+2/2

y=1/2

therefore Q(x,y)=(1/2,1/2)

as P=Q

therefore

we can say that the diagonals have the same mid point
