These examples of adjacent angles will add up to values other than 90, 180 or 360 degrees. Generally, if you are required to calculate other types of adjacent angles, your instructor or textbook ...

It's possible to demonstrate and prove mathematically that the angle sum of every triangle is 180 degrees. The techniques used are useful for solving all kinds of other geometry problems too.

A 180-degree angle means that there is no difference ... Horizontal and vertical angles are often not the same. For example, looking down on a screen may have less of a viewing angle than from ...

if you were to use the figure of a circle with a sum of 360 degrees as an example, two supplementary angles add up to 180 degrees to form a measure that splits the circle perfectly in half.
