Draw any straight line through the point. The sum of the angles at the point are the sums of the angles on each side of the line - which are known to be 180o. Thus: the sum of the angles at the point = the sum of the angles of each side of the line = 180o + 180o = 360o The sum of the a
180 degrees
Because that is what a straight line (or straight angle) is.
Sum of adjacent angles on a straight line.
a straight line
If the two angles sum adds up to 180 degrees, then they are supplementary angles.
The sum of the three constitutive angles of a planar triangle is always equal to 180 degrees or two right angles. And there are two things in it as well. they are diagonal and a exterior angle
a straight line or supplementary angles...which equal to 180 degrees.
The sum is two straight angles or 360 degrees.
Two angles whose sum is 180 degrees are called supplementary angles. When two angles are supplementary, it means that the sum of their measures equals 180 degrees. This relationship is often used in geometry to solve for unknown angles or to identify complementary angles.
a line with an angle in it would technically be 2 linesA circle has a sum of angles that add up to 360 degrees and it is not a straight line.
The sum of supplementary angles is 180° . The supplementary angle of 93° is 180 - 93 = 87°
