A quadrilateral has vertices
Find the lengths of the diagonals,to the nearest tenth?
Maybe re-wording this question will help you out. Find the distance between two points:
a)(-4,3) and (5,-4)
b)(-3,-2) and (3,5)
I'm sure your teacher gave you this formula:
d = sqroot [(x2 - x1)^2 + (y2 - y1)^2]
where x and y are defined as (x,y) in the coordinate. x2 just mean the x in the second coordinate.
