You can put this solution on YOUR website!
Complementary angles, by definition, add up to 90 degrees, so the complement of 89 degrees is 90 - 89 = 1 degree.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Similarly, you'll see the other definition, supplementary angles. They are similar, except that the two angles sum up to 180, not 90.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The concept of complementary and supplementary angles is extremely useful in geometry. However I rarely see these words in advanced geometry problems, mainly because the question will be worded something like \"Prove that ABC + CBD = 90\" instead of \"Prove that ABC and CBD are complementary\" (possibly because foreign students might not know the terminology). But on certain problems involving parallel lines or right angles, this concept is crucial. \n" ); document.write( "
