Question

.

Answer 1

The centroid of ANY triangle has the following properties:
1. It is the intersection of all three medians, i.e. lines which join a vertex and bisects the length of the opposite. For example, AD is a median, P is the centroid, and mBD=mDC
2. The distance between the centroid and the vertex is twice the distance between the centroid and the opposing side. For example, mAP=2(mPD).

With the second property, we can say for
#11.
QN=9, so QP=(1/3)PN=3, PN=2QP=6.
Want to try the other ones while I watch?

Answer 2

im confused ;-;

Answer 3

Can you identify a median from my diagram?

Answer 4

P?

Answer 5

That is the centroid.
Median is a line that joins a vertex and the opposite side, AND passes through the centroid.
Can you find one?
