Angles on one side of a straight line always add to 180 degreesExample: 30° + 150° = 180° When a line is split into 2 and we know one angle, we can always find the other one.Example: We know one angle is 45°, what is the other angle "a" ? Angle a is 180° − 45°...

The meaning of CORRESPONDING ANGLES is any pair of angles each of which is on the same side of one of two lines cut by a transversal and on the same side of the transversal.

If ∠H = 60°, ∠E = 120° since those two are on a straight line, they are supplementary. Now, ∠A = ∠E = 120°. ∠A and ∠E are corresponding angles. When corresponding angles are equal, the lines are parallel. Likewise, we can prove using other angles too. ...
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 toler...
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!
A line is a straight path of points that goes on and on in 2 directions. A line segment is part of a line with two endpoints. A ray is part of a line that starts at one endpoint and continues on forever in one direction only. Now, what is an angle? An angle is the figure form...
