Question

A triangle has vertices on a coordinate grid at G(-5, -5), H(8,-5), and I (8,0)..

What is the length, in units, of GH?

Answer 1

If we are trying to find the length of GH, we have to use the distance formula! The distance formula is d = √((x^2-x^1)^2 + (y^2-y^1)^2)

As such, our x^1 and y^1 are the same as G, or (-5,-5)

Our x^2 and y^2 is the same as H, or (8,-5)



Our length is 13 units
