There is a unique positive number corresponding to every pair of points
The points on a line are in a one-to-one correspondence with real numbers, so that number differences measure distances.
The shortest path in-between two lines How do you measure segments
Using rulers, inches, feet, yards, meters....
How do you measure angles?
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.
Segments or angles with the same measure
acute angle Measure is greater then 0 degrees and 90 degrees right angle Measure is
obtuse angle Measure is greater then 90 degrees and less then 180 degrees
straight angle Measure is
reflex angle Measure is greater then 180 degrees less then
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.
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)
