Geometry Flash Cards 2 Essay Geometry Flash Cards 2 Essay The Distance Postulate There is a unique positive number corresponding to every pair of points The Ruler Postulate The points on a line are in a one-to-one correspondence with real numbers, so that number differences measure distances. Distance The shortest path in-between two lines How do you measure segments Using rulers, inches, feet, yards, meters.... How do you measure angles? Protractor what does the size of an angle represent The amount of turning you would have to do if you where at the vertex The Angle measure postulate There is a unique number between 0 and 360 corresponding to every angle the protractor postulate There is a one-to-one correspondence between the raysin a half-rotation and the real numbers from 0 to 180 inclusive, so that number differences measure angles. Congruent Segments or angles with the same measure acute angle Measure is greater then 0 degrees and 90 degrees right angle Measure is 90 degrees obtuse angle Measure is greater then 90 degrees and less then 180 degrees straight angle Measure is 180 degrees reflex angle Measure is greater then 180 degrees less then 360 degrees Bisector Any point, segment, ray, line, or plane that contains the midpoint of the segment. Trisect Two point, segments, rays, or lines that divide a segment into three congruent segments. Circle The set of all points in a plane having the same distance/radius from a fixed point/center. polygon union of segments meeting only at endpoint such that 1. No more then two segments meet at one point and 2. Each segment meets exactly two other segments. (closed shape)
