POINTS, LINES, & RAYS
POINT A point is a location in space that has no length, width, or height. READ: point C WRITE: C C
LINE A line is a straight, continuous, and unending path made up of a collection of points. READ: line CD WRITE: CD CD
LINE SEGMENT A line segment is part of a line and has two endpoints. READ: line segment CD WRITE: CD CD
RAY A ray is part of a line made up of one endpoint and all the points on one side of it. READ: ray CD WRITE: CD CD
PLANE A plane is a flat surface made up of a continuous and unending collection of points. READ: plane JKL WRITE: plane JKL ·L·K ·J
INTERSECTING LINES Intersecting lines have one point in common. READ: Line AB intersects line CD at point E. D B C E A
PERPENDICULAR LINES Perpendicular lines intersect at right angles. READ: Line RT is perpendicular to line WX. WRITE: RT WX. W T X R
PARALLEL LINES Parallel lines lie in the same plane but never intersect. READ: Line MN is parallel to line PQ. WRITE: MN PQ. P N Q M
Points Lines Planes Circles Polygons Congruency Similarity.
Geometry Point Line Line segment Ray Plane Parallel lines Intersecting lines Angles.
Line- a straight path that goes in two directions without ending. A B AB Read: “Line AB”
