Lines and RaysLINE: A straight path extending in bothdirection with no endpoints.LINE SEGMENT: A part of a line thatinclude two points, called endpoints,and all the points between them.
About raysRAYS:A part of line, with one end point, that continues without end in one direction.
More about linesINTERSECTING LINES: Lines that cross. PARALLEL LINES: Lines that never cross and always the same distance apart.
Perpendicular linesTwo that intersect to form four right angles.
The figure formed when two rays sharethe same end point Right Angle: An angle that forms Square corner. Acute Angle: An angle less than a right angle. Obtuse Angle: An angle greater Than a right angle.
Complementary Angles Two angles called complementary angles if the sum of their degree measurements equal 90 degrees. Example: 58 32These two angles can be 58Pasted together to form 32Right angle.
Supplementary AnglesTwo angles are called supplementary angles if the sum of their degree measurements equal 180 degree.Example: 139 41These two angles can be pasted 139 41Together to form straight line
Vertical opposite anglesTwo angles formed by two intersecting lines having no common arm are called vertical opposite angles.Example: If two lines intersect then vertical opposite Angle are always equal.
Adjacent anglesTwo angles in a plane are called adjacent angles, if They have a common vertex They have a common arm, and Their other arms lie on the opposite sides of the common arm.Example: A d s e
