Question

Triangle HIJ has coordinates H(-3,5), (8,2), and J(-3,-5). Find

the length of each side.

HI = ?
IJ = ?
HJ = ?

Answer 1

H (x= -3 , y=5)

I (x=8 , y=2)

J (x= -3 , y= -5)

D is the distance between the 2 points so just plug in the x and y cords of each of the corresponding points

so for (HI)

you plug in 2 on the red x

and 8 on the red y

then -3 in the blue x

and 5 in the blue y
