- Knowledge of the lengths of the sides of the triangle.

Instruction

1

To calculate the length of the median formula is applied (see Fig. 1), where:

mc is the length of the median;

a, b, c be the sidelengths of a triangle.

mc is the length of the median;

a, b, c be the sidelengths of a triangle.

Note

The medians of a triangle have the following properties:

1) any of the three medians divides the original triangle into two equal size triangle;

2) All medians of a triangle have a common intersection point. This point is called the center of the triangle;

3) the Medians of a triangle divide it into 6 equal triangles. Equal are called geometric shapes with equal areas.

Useful advice

If the triangle is an isosceles triangle, its medians are equal. In addition, in such a triangle the medians coincide with the bisectors and heights.

The angle bisector is the ray that emanates from any vertex of a triangle and forming it divides the angle in half.

Under the height of a triangle is meant the segment, which is drawn from the vertex of the triangle perpendicular to the opposite side.
