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.
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.
straight line indicates 180o
a straight line or supplementary angles...which equal to 180 degrees.
A straight line in angles represents 180 degrees.
That the corresponding angles are equal and that the alternate angles are equal and that angles on a straight line add up to 180 degrees.

Angles that add up to 180 degrees are called supplementary angles.
Yes because angles on a straight line add up to 180 degrees
It is a straight line which divides an interior angle of the triangle into two angles of equal measure.
a straight line or supplementary angles...which equal to 180 degrees.
All The Angles On A Straight Line Add Up To 180 Degrees.
A straight line in angles represents 180 degrees.
The sum of the angles in a rhombus equal a straight angle (180o).
