VIDEO: How do you draw a bisector?

What is a bisector?

• In the geometry learn how to straight, angle, Points, distances and levels are related.
• The geometry that is taught in school is called elementary geometry.
• A bisector is a straight line that connects one corner of a triangle with the center of the opposite side.
• In the case of a triangle, there can be 3 bisectors. These intersect at a special point, the so-called center of gravity.
• The distance between a corner and the center of gravity is always longer than the distance between the center of gravity and the center of one side of the triangle.

You have seen through the usual vector calculation, but how do you go through the vectors ...

Now read how to draw a bisector.

A bisector is slightly drawn

A side bisector is easily drawn with a pair of compasses.

1. To do this, take the compass and set the radius first.
2. To do this, pierce the compass at point A and open the lead tip to point B. The radius is now the length of AB.

3. Now draw a complete circle, starting from the piercing hole A.
4. Now draw another circle, starting from point B. It is important that you do not change the radius of the compass.
5. Now pierce point C and draw a complete circle.
6. The circles intersect in 3 places.
7. Use a ruler to draw the intersections up to the upper edges of the lines A, B and C. These are exactly the midpoints of the routes.
8. To draw the bisectors, connect the midpoints of the lines with the opposite corners.
9. At the end you get the center of gravity in the triangle, where the 3 bisectors meet.
