Segment addition
|
AB+BC=AC
|
|
|
Protactor
|
If there is a straight segment, then any rays that are starting in the middle of that segment is an angle. The rays can be paired with real numbers from 0 to 180.
|
|
|
Angle addition
|
If a point lies in the middle of angle than there are two interior angles, and added together they equal the largest angle.
if there is a straight segment and b is a ray coming out of that segment then the adjenct angles= 180. |

5
|
Line- two points
plane- 3 points they can't all be linear space- 4 points not all on the same plane |
|
|
6
|
through any two points is a line
|
|
|
7
|
through 3 points is atleast one plane and through 3 noncolinear there is only 1
|
|
|
8
|
if there are two points in a plane, then a line that contains those points are in that plane
|
|
|
9
|
if 2 plane intersect, then a line is formed
|
|
|
Theorem 1
|
if 2 line intersect only 1 point is formed
|
|
|
theorem 2
|
A line and a point not on that line make a plane
|
|
|
Theorem 3
|
if two lines intersect then only 1 plane contains them
