The consecutive angles are those with one vertex and one common side. When the angles are ordered in a certain way, they will be consecutive if each angle is successive with the other. When the angles are consecutive and interior, it is when two lines are crossed by another transversal call but within both lines.
The sum of the consecutive angles is equivalent to the angle comprised by the infrequent sides of the angles. For two angles to be added they necessarily have to be consecutive. At the time of classifying consecutive angles, other classes of angles can be found, such as adjacent angles, which also have the property that their lines are located next to each other. On the other hand, complementary angles cannot be linked to the consecutive term, since this class of angles in some cases can have the same vertex line but not in other cases.
When referring to the triangles, they have consecutive external angles associated with the relevant internal angles to each vertex, thus achieving that the side they have in common serves as the side of the triangle, thus determining an acute and an obtuse side. It is recommended that if the disparity between two consecutive angles is 50º sexagesimal, when drawing an angle that has a greater extension of its angle to the naked eye and that the disparity with the other angle is 50º sexagesimal, of This way you have to draw the angle, it is not advisable to draw the two angles with the same amplitude since this would be difficult to reach the answer.
