A bisector is a point that divides a line segment into three equal parts. Make an arbitrary triangle with this line segment as the center line and draw another center line of the triangle. Then the two center lines intersect at point A, take this point as the center, make a circle with the distance from the line segment to the bottom of the triangle as the radius, and intersect at point B, then point A and point B are the bisector of the line segment.
How to draw the bisector?
The above are the knowledge points that I have sorted out. Thank you for reading.
