Mathematics / Lines and Angles

Mathematics / Lines and Angles

A line is a one dimensional geometrical object with negligible width and depth.
When 2 lines meet at a point, they form an angle at that point. The point is called the vertex of the angle and the 2 lines are the arms. There are different types of angles based on the position of the arms.

Learn about the angles formed when two lines intersect and the relationship between these angles.

A transversal intersecting two parallel lines has the following properties:

• corresponding angles are equal
• alternate interior angles are equal
• interior angles on the same side of the transversal are supplementary
Using the above properties, prove a variety of theorems.   Exercises
