Homework Statement
A triangle is defined by the following vertices: (40,85), (15,0), and (-40,35). Is it a right triangle?
Homework Equations
Distance Formula:
Given two points A(1,2) and B(3,4) Find the distance using the below forumla.
d(A,B) = sqrt((x2-x1)^2 + (y2-y1)^2)
The Attempt at a Solution
1) We have X(40,85), Y(15,0), and Z(-40,35)
2) We can use the distance formula b/c it is derived from pythagorean therom (which determines if a triangle is a right triangle).
3) Using the distance formula for three vertices given two components for each might look something like this:
d(x,y,z) = sqrt((x3-x2-x1)^2 + (y3-y2-y1)^2)
