First, the judge (2 points for each empty, a total of 26 points) 1. The intersection of three straight lines must have three intersections. () 2. The length of the line segment AB is the distance from point A to point B. () 3. When line segment AM = MB, M is the midpoint of line segment AB. () 4. Flat angle is the beginning and the end of the reverse of each other to extend the line angle. ()
