you always add on 180 degrees
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 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.
In a triangle, the sum of the three angles is always 180 degrees. This relationship is known as the angle sum property of a triangle.
positive and negative angles of 87 degrees
The relationship between molecular geometry and O2 bond angles is that the molecular geometry of O2 is linear, meaning that the bond angle between the two oxygen atoms is 180 degrees.
112.5 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).
