Best Answer

The first angle is ( X ), a variable number where

the other angle is (180-X)

The sum of these two angles will always be 180* , X+180-X=180

In this case the variable number (X) is between negative infinity & positive infinity.

for eg. if the first angle is 1* the other angle would be 180-1, or 179*, & the sum of 1* and 179* is 180*

The sum of the internal angles of any triangle is 180 degrees. Any rectangle has four 90 degree internal angles, totalling 360 degrees.

Supplementary angles have a sum of 180 degrees.

Two angles are complementary if the sum of their measures is 90 degrees.Two angles are supplementary if the sum of their measures is 180 degrees.

The sum of the measures of the interior angles is (n-2)*180 degrees, where n is the number of sides. Thus, if the sum of the interior angles is S, then n = S/180 + 2
