Coordinates : A(1,2) B(-5,6) C(7,-4) D(-2,t) - All are taken in order
gradient of AB = (6-2)/(-5-1) = 4/-6 = -⅔
since it is quadrilateral, AB//CD
gradient of CD = -⅔
equation of CD : y-(-4)=-⅔(x-7)
y+4=-⅔x+14/3
y=-⅔x+⅔
now, sub x=-2 from D(-2,t)
since t is the y-coordinate of point D
t=-⅔(-2)+⅔
t=2
Therefore, t=2
Answer:
This is solved by Distance Formula
D²=(x2_x1)²-(Y2-y1)²
So D²= (-5-0)²-(1-1)²
D²=25
We can solve D by square root so
D=5
the Distance or length between a and b was 5
you can solve for c and d in a such way
