3 Points Of The Triangle
The median of a triangle connects a vertex (corner) of the triangle to the midpoint of the opposite side. This means that each triangle has three medians, one from each vertex. To find the midpoints of the sides, it is helpful to draw a rough sketch of the triangle.
To find the midpoint of a side, you can use the following formula:
Midpoint = (x₁ + x₂)/2, (y₁ + y₂)/2
where (x₁, y₁) and (x₂, y₂) are the coordinates of the endpoints of the side.
Once you have the midpoints, you can draw lines from each vertex to its corresponding midpoint, and these are called the medians.
