## xxScarlett 2 years ago So this is a question in the "Looking Ahead" (extension) section of my homework. I have a few questions like this on the worksheet but just answering this one would help me a lot. Any help provided would honestly be great. :) 1. There is a square HJKL. The coordinates of the points are as follows H(0,2), J(2,6), K(6,4), L (4,0). a. What is the length of each diagonal? b. What is the slope of each diagonal? c. Are the diagonals congruent perpendicular bisectors?

1. ByteMe

do you know the distance formula?

2. xxScarlett

$\sqrt{(x2-x1)^2 + (y2-y1)^2}$ Right?

3. Directrix

Yes. I would draw the square first to see which points are endpoints of diagonals. |dw:1360722505087:dw|

4. Directrix

I used the distance between two points online calculator to get the length of diagonal LJ. http://easycalculation.com/analytical/distance.php

5. Directrix

Use it to calculate the length of diagonal HK.
