There are four pairs of vertex angles, two pairs of internal stagger angles, four pairs of apposition angles and two pairs of internal angles in the same side



The following proposition is correct: A. equal internal stagger angle B. equal angle is opposite vertex angle C. when three straight lines intersect, they must produce the same position angle, internal stagger angle and the same side
16. The following proposition is correct ()
A. Equal internal angle
B. Equal angles are opposite to vertex angles
C. When three straight lines intersect, they will produce the same position angle, internal stagger angle and internal angle on the same side
D. The two lines are parallel
A: If the two angles are equal, then they are staggered;
B: If two angles are equal, then they are opposite the vertex;
C: If three straight lines intersect, it will produce the same position angle, inner stagger angle and the same side inner angle;
D: If the same angle is equal, then the two lines are parallel;


A. If two angles are equal, they are wrong
B. An equal angle is a mistake for a vertex angle
C. When three straight lines intersect, there will be errors in the same position angle, internal angle and internal angle on the same side
D. The same position angle is equal, two straight lines are parallel correctly



Fill in the blanks for the concept of vertex: among the four corners formed by the intersection of two lines, the two corners with common fixed point but without () side are opposite vertex
