Properties of Supplementary Angles

Various properties of Supplemenytary Angles are:

  • Two supplementary angles are those that, when combined, have a sum equal to 180 degrees.
  • Some of them are located in place which are directly connected while others are located at places which are not directly joined.
  • What one angle is the sum of the other angle Given one angle and the supplement of that angle is another angle.
  • If two angles are equal to the sum of the same angle both are equal or congruent.
  • Two supplementary angles are those whose sum is equal to 180o and when laid side by side, their angle will span the entire line.
  • Anyone of you who is a right angle, then its supplement is also a right angle.
  • When discussing supplementary angle pairs, neither of the two angles can be acute and the other cannot be obtuse.

Supplementary Angles

Supplementary angles are two angles whose measures add up to 180°. In other words, if you have two angles, and when you add their measures together you get 180°, then those angles are considered supplementary. For example, if one angle measures 120°, the other angle must measure 60° to be supplementary to it.

What are Supplementary Angles?

Supplementary angles are two angles that, when added together, equal 180 degrees. For instance, if you have one angle measuring 60 degrees, its supplementary angle would measure 120 degrees, because 60 plus 120 equals 180 degrees....
