1. The problem statement, all variables and given/known data A triangle is defined by the following vertices: (40,85), (15,0), and (-40,35). Is it a right triangle? 2. Relevant 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) 3. 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) ~107?
