The sum of the three angles is 180 degrees. There are other relationships that can be derived from this.
The sum of the interior angles of a triangle is equal to 180 degrees.
112.5 degrees
They both add up to 180 degrees when on a staight line.
The internal angles of a quadrilateral (a plane figure with four straight sides) is 360 degrees, whatever the relationship between the sides.
The relationship is that they are supplementary angles because angles on a straight line add up to 180 degrees

The sum of the interior angles of a triangle is equal to 180 degrees.
positive and negative angles of 87 degrees

They both add up to 180 degrees when on a staight line.
There isn't one. The sum of the exterior angles is always 360 degrees, the sum of the interior angles varies depending on the number of sides.
The internal angles of a quadrilateral (a plane figure with four straight sides) is 360 degrees, whatever the relationship between the sides.
The opposite angles are congruent and all add to 360 degrees
Essentially, none. Every negative angle can be made positive by adding 2*pi radians (or 360 degrees, or a multiple).
The angles are called obtuse.Another Answer:Angles from 180 degrees to 360 degrees are reflex angles
An acute angle is between 0 and 90 degrees. Angles between 90 and 180 degrees are called obtuse angles.
