Question 1164769
<font face="Times New Roman" size="+2">


Use the midpoint formulas to find the coordinates of the midpoints of each of the sides of the triangle:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x_m\ =\ \frac{x_1\,+\,x_2}{2}]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y_m\ =\ \frac{y_1\,+\,y_2}{2}]


Where *[tex \Large (x_m,y_m)] is a midpoint of one of the triangle sides and *[tex \Large (x_1,y_1)] and *[tex \Large (x_2,y_2)] are the vertices that are the endpoints of that side.


Once you have the midpoints, you can use the distance formula:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ d\ =\ \sqrt{(x_v\,-\,x_m)^2\,+\,(y_v\,-\,y_m)^2}]


Where *[tex \Large (x_v,y_v)] is any vertex and *[tex \Large (x_m,y_m)] is the midpoint of the side opposite that vertex.

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