Question 470232


    Two angles are {{{complementary}}} if the {{{sum}}} of their angles equals {{{90}}}o.

    If one angle is known, its complementary angle {{{can}}} be {{{found}}} by {{{subtracting}}} the measure of its angle from {{{90}}}o.


    Example: What is the complementary angle of {{{43}}}o?
    Solution: {{{90}}}o  -  {{{43}}}o  =  {{{47}}}o


    Two angles are {{{supplementary}}} if the {{{sum}}} of their angles equals {{{180}}}o.

    If one angle is known, its supplementary angle can be found by subtracting the measure of its angle from {{{180}}}o.

    Example: What is the supplementary angle of {{{143}}}o?
    Solution: {{{180}}}o  -  {{{143}}}o  =  {{{37}}}o
