What is opposite vertex angle
Two sides of an angle are the opposite extension lines of the other angle. These two angles are opposite vertex angles. After two lines intersect, there is only one common vertex, and both sides of the two angles are opposite extension lines. Such two angles are called opposite vertex angles
