The sum of the measures of the angles in any triangle in the plane is 180 degrees. If two angles are 15 and 85 then their sum is 100 degrees and 180-100=80 degrees
Sum of adjacent angles on a straight line.
I assume you mean a TRIANGLE. The angles in a triangle will sum up to 180 degrees. So sum your two angles and subtract that from 180.
Supplementary angles have a sum of 180 degrees.
The sum of all the internal angles of a triangle is 180. If two of them are each 50, then the third one must be 180 - (2 x 50) = 180 - 100 = 80.
Supplementary angles.

No, these are two quite different things. "Supplementary" means that the sum of the angles is 180 degrees. The angles need not be consecutive; on the other hand, two consecutive angles can have any measure, not always 180 degrees.No, these are two quite different things.

They are a supplementary pair of angles.

Two angles whose sum measure is 180 Example: 45 + 135=180
Sum of adjacent angles on a straight line.
Right angles are 90°. The total measure of a triangle is 180°. So, the sum of the other two angles must equal 90°.
SUPPLEMENTARY ANGLES are two angles the sum of whose measures is 180 degrees.

Yes. The general rule for angles is that the sum of the angles must be 180 degrees.
