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.
Angles that add up to 180 degrees are called supplementary 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°
