Geometry - the branch of mathematics that deals with the study of points, lines, angles, surfaces, and solids, A point  - A position or location on a plane , A plane - Any flat 2D surface , A line - A straight, indefinitely thin one dimensional figure that contains points and continues forever in both directions  , A line/ray/segment - can be named by any 2 points on that Line or by a lowercase letter , A ray - A part of a line that starts at a fixed point and goes on forever in only one direction , A line segment - is a part of a line that has two endpoints , to measure a line/line segment you can use a - ruler, To measure angles you use a - protractor , Colinear - if points are all on the same straight line then they are said to be , Perpendicular lines are - lines that meet at a 90 degree angle , Parallel lines - lines that stay the same distance apart and that will never meet , Angle - a measure of rotation , Vertex - the point where the arms/ray of an angle meet , arms of the angle - the two rays that form the angle are called , Null angle , acute angle , right angle , Obtuse angle , Straight angle , Reflex angle , Full angle/ rotation , Ordinary Angle , Supplementary Angles ,
