Question 601486
<font face="Times New Roman" size="+2">


Use the distance formula on each of three pairs of vertices:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ d\ =\ sqrt{(x_1\ -\ x_2)^2\ +\ (y_1\ -\ y_2)^2}]


where *[tex \Large \left(x_1,y_1\right)] and *[tex \Large \left(x_2,y_2\right)] are the coordinates of the given points.


Hint:  Two of your calculations are trivial because one of the sides of the triangle is horizontal and the other is vertical.


Once you have the three distances calculated, pick the largest one.

My calculator said it, I believe it, that settles it
