Geometry(points, lines, segments, etc.)3 Things you MUST know about geometry: The way you DRAW the geometric ideaThe way you SAY the ideaThe way you WRITE the idea*Get any of these off just a bit and you’ve given the wrong answer.Let’s see what this means .
DefinitionDRAWSAYPoint- is an exact location in space.WRITEpoint CCLine- a straight set of points that goes on forever in two directions.Line BCBCLine segment RSRSLine Segment- a part of a line and has two enpointsRay- a part of a line. It has only one endpoint and extends forever in one direction.Ray JKJKPlane LMNLMNPlane- an endless flat surface.Parallel lines- Lines that never cross and stay an eqaul distance apart.Line AD is parallel to line VW.AD VW
Intersecting Lines- Lines that pass through the same point.Line PE interesects line QC. PE interseects QC.Perpendicualr lines- Lines that are intersecting, that form a 90 or right angle.Line RS is perpendicular to line FH. RS FH* a Ray must always be writen with the endpoint letter 1st, then the continuousend next. All other may be written in either direction.
