You can use GeoGebra
to find the centroid and medians of a triangle.
GeoGebra
Instruction 1
Algebra View
and Graphics View
under View
in Menu
. Polygon
. Then, you need to click on three points in Graphics View
where you want the corners of the triangle to be. Finally, finish the triangle by clicking on the same point that you started with. Midpoint or Center
(it is located in the same menu as Point
). Construct the midpoints , , and by clicking , , and , in that order. Segment
(it is located in the same menu as Line
). Construct the line from to the midpoint on the opposite side . Then, construct the line from to the midpoint on the opposite side . Finally, construct the line from to the midpoint one the opposite side . These lines are the medians. Intersect
. Construct the point of intersection of two medians. This point is the centroid.
