In which figure is point E the centroid of the obtuse triangle, triangle KLM?

OpenStudy (anonymous):

Which triangle

OpenStudy (anonymous):

The centroid is where the 3 medians of a triangle intersect. A median goes from one vertex to the midpoint of the opposite side.

OpenStudy (anonymous):

So... which one would it be lol.

OpenStudy (anonymous):

i dont know how to do this stuff.

OpenStudy (anonymous):

Just pick the one that looks similar to this. |dw:1339819602761:dw| Only one of them has the tick marks. The tick marks show congruence. A median bisects the opposite sides.

OpenStudy (anonymous):

If it has three tick marks, it's congruent to the other one that has three tick marks.

OpenStudy (anonymous):

the only one that is similar to that one is the last one

OpenStudy (anonymous):

Are you not paying attention to the tick marks?

OpenStudy (anonymous):

OpenStudy (anonymous):

dont they mean congruency?

OpenStudy (anonymous):

Yeah. Medians bisect sides. THis means that it splits the side into two congruent sides.

OpenStudy (anonymous):

so which triangle is it

OpenStudy (anonymous):

Ok, there is only one triangle with the marks that I was talking about. Which one is it?
