supplementary angle การใช้

When the lines are congruent and several supplementary angles.
If one vector is pointing the wrong way at a point, you will get the supplementary angle at that point.
For example, two lines can intersect in no more than one point, intersecting lines have equal opposite angles, and adjacent angles of intersecting lines are supplementary angles.
Supplementary angles are formed when a ray shares the same vertex and is pointed in a direction that is in between the two original rays that form the straight angle ( 180 degree angle ).
The base angles of an isosceles trapezoid are equal in measure ( there are in fact two pairs of equal base angles, where one base angle is the supplementary angle of a base angle at the other base ).
