Different types of angles in geometry

In geometry we have lots of concepts to know. Like types of angles, properties etc. Now we will move some other topics of angles such as Alternate exterior angles, alternate interior angles.

Alternate Exterior angles: If any pair of parallel lines are intersected by any other third line such as in the below figure. then the angle A and D are called alternate exterior angles. Angle B and C are also called alternate interior angles

                                         
Alternate Interior angles: If any pair of parallel lines are intersected by other straight line, as given below, then the angle A and D are called alternate interior angles..

This is all about two types of angles in geometry. Further we will discuss on some different topics of math.
