AM is a median of a triangle where A is one vertex and
M is the midpoint of a side of a triangle opposite vertex A. If the distance from the centroid of the triangle
to M is 5 units, how long is the median AM

I have: The centroid, is the balance point, or center of gravity, of a model of the triangle and which is two-thirds the distance from each vertex to the opposite side. so it is 15 units. I am so confused can you help

• Geometry -

point z is the centroid of triangle ABC,CA=20,AD=12 and BE=9 what is the perimeter AZE?

• Geometry -

I believe the correct answer is 127 units for the perimeter.
