Lines and Angles
Line: A-Line is a collection of points going endlessly in both the direction along a straight path. Example of line
Line segment: Line segment is also a part of the line but it has two endpoints.
A ray: A ray is also a part of a line. It begins from one point and travels endlessly in the other direction.
Supplementary Angles: Two angles are called supplementary if the sum of their measurement is equal to 1800 example: 1100 and 700
Complementary Angles: Two angles are said to be complementary if the sum of their measure is equal to 900
