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.

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.

Only one of them has the tick marks. The tick marks show congruence. A median bisects the opposite sides.

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

Are you not paying attention to the tick marks?

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?
