Two angles are supplementary 2009-01-08
From Stephanie:
two angles are supplementary, one of the angles is 30 degrees more than double the other angle. find the first angle, the second angle the complement of the given angle.

Supplementary angles 2008-11-10
From Anna:
<A and <B are supplementary angles. Twice the measure of <B is one-fourth the measure of <A. Find the measure of both angles.

Complementary and supplementary angles 2007-04-26
From Tracey:
I have looked at your answers for students asking if groups of more than two angles can be considered either complementary or supplementary. Your answer is basically "no" because of historic definition. However, I present to you the following case to consider:

Segments AB, CD and EF intersect at point G creating 6 angles numbered 1-6 in a clockwise manner. If Angle 1=25 degrees, and angle 2 = 106 degrees, would the only way to calculate the measures of angles 3 and 6 not be to consider the definition of supplementary angles? And, if one was to be doing a proof of this, would not the reason be "definition of supplementary angles"?

This, then, creates a group of 3 angles that are supplementary.

Help me correct my logic if it is flawed.

The angle between two forces 2005-01-19
From Abraham:
One force of 20 pounds and one force of 15 pounds act on a body at the same point so that the resultant force is 19 pounds. Find, to the nearest degree, the angle between the two original forces.

Supplementary angles 2004-09-23
From Rosemary:
Is the term supplementary angles only applicable to 2 angles (ie. a pair of angles) or can it be used when talking about 3 or more angles that add to make 180 degrees?

What are adjacent angles that equal 360 called? 2000-11-22
From David:
I know that supplementary angles add to 180 degrees and that commplementary angles add up to be 90 degrees, but what are adjacent angles that equal 360 degrees called?
Answered by Chris Fisher.
Supplementary angles 2000-05-09
From Suzanne:
We know that: Supplementary angles are two angles whose sum equals 180 degrees and complementary angles are two angles whose sum equals 90 degrees. Are supplementary and complementary angles necessarily adjacent? or can they be non-adjacent?
Answered by Chris Fisher.
Complementary and Supplementary Angles 1998-10-21
From Christina Saunders:
I am in 9th grade and my math teacher wanted us to find out why complimentary angles are called complimentary and why supplimentary angles are called supplimentary. I have looked everywhere and asked numerous people, but I have yet to find an answer. My math teacher said it had something to do with trigonometry. Do you have an answer for me?
