Angles on one side of a straight line always add to 180 degrees. 30° + 150° = 180°. When a line is split into 2 and we know one angle, we can...

Dangles occur on line features when a node at either end is not connected to another line feature. This can occur if data has been moved or a feature has been extracted incorrectly. The Find Dangles check searches an input feature class for dangling nodes that fall within a specified ...

If we take one of the shapes, say a regular pentagon, then as the total angles is 540°.Then one of the internal angles is 540÷5 =108. Then the external angle will be 72° as the angles on a straight line always equal 180.108°72 ...
An angle is a geometrical figure formed when two rays meet at a common point called vertex. Let's know about angles, their parts, types, construction using examples!
Learn about Alternate Exterior Angles: When two lines are crossed by another line (called the Transversal), Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal.
