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 ).
• Since the sine of an angle and the sine of its supplementary angle are the same any angle of rotation that maps one of the lines into the other leads to the same value of the spread between the lines.
• Since the sine of an angle and the sine of its supplementary angle are the same, any angle of rotation that maps one of the lines into the other leads to the same value for the spread between the lines.
• These are the internal angle bisectors at two opposite vertex angles, the external angle bisectors ( supplementary angle bisectors ) at the other two vertex angles, and the external angle bisectors at the angles formed where the extensions of opposite sides intersect.
• When a wave train strikes a wall at an oblique angle, the reflected wave train departs at the supplementary angle causing a cross-hatched wave vortices, can erode material from the seabed and transport it along the wall, undermining the structure until it fails.
• The " exterior " or " external bisector " is the line that divides the supplementary angle ( of 180?minus the original angle ), formed by one side forming the original angle and the extension of the other side, into two equal angles.
• Knowing two spreads allows the third to be calculated by solving the associated quadratic formula but, since two solutions are possible, further " triangle spread rules " must be used to select the appropriate one . ( The relative complexity of this process contrasts with the much simpler method of obtaining a supplementary angle of two others .)
• In Euclidean geometry, an "'ex-tangential quadrilateral "'is a external angle bisectors ( supplementary angle bisectors ) at the other two vertex angles, and the external angle bisectors at the angles formed where the extensions of opposite sides intersect ( see the figure to the right, where four of these six are dotted line segments ).
• That is, for the latitude ( the North / South coordinate ) the magnitude of the angle remains the same but N is changed to S and vice versa, and for the longitude ( the East / West coordinate ) the angle is replaced by its supplementary angle while E is exchanged for W . For example, the antipode of the point in China at ( a few hundred kilometres from Beijing ) is the point in Argentina at ( a few hundred kilometres from Buenos Aires ).
