The sum of the measures of angles on a straight line is 180 degrees. Therefore, if angle is equal to 71 degrees, the other is equal to 180 - 71 = 109 degrees.
Because 90 degrees is half of a straight line. A straight line is equal to 180 degrees. 180 divided by 2 = 90.
Well, since one straight line has 180 degrees, two would equal 360 degrees.
It would be a straight line.
a straight line or supplementary angles...which equal to 180 degrees.
Angles on a straight line always add up to 180 degrees. This is because a straight line represents a half-turn, and the total measure of angles around a point is 360 degrees. Therefore, the angles on one side of the straight line must sum to half of that total, equating to 180 degrees.

There are 180 degrees on a straight line.

There are no degrees because it is a STRAIGHT LINE
A straight angle (180 degrees) makes a perfectly straight line. Any degree below 180 degrees (0-179 degrees) is NOT a straight angle NOR a straight line. straight angle = 180 degrees straight angle = straight line 180 degrees
If you took the three angles of a triangle and glued them on a piece of paper side by side the outer sides would make a straight line. A triangles three angles add up equal 180 degrees. A straight angle,line, equals 180 degrees.
There are 180 degrees on a straight line
An angle of 180 degrees has no name, but its subtending lines would form one straight line.
