If a+c = b+d, then... |
a=b and c=d. |
|
|
|
If a-c = b-d, then... |
a=b and c=d. |

|
Betweenness of Points Theorem |
States that if A-B-C, then AB + BC = AC. |
Between does not necessarily mean the middle. |
|
|

a given angle. |
|
|
|
Angle-Addition Post. |
If a point D lies in the interior of an angle ABC, then m<ABD + m<DBC = m<ABC. |
|
|
|
There is one and only one bisector... |
for a given angle. |

2 objects. |
|
|
Transitive Property |
If a = b and b = c, then a = c. |
3 objects. |
|
|
If two lines are perpendicular, then... |
they meet to form right angles. |
|
|
|
If two lines intersect, then... |
the vertical angles formed are congruent. |
|
|
|
In a plane, there is exactly... |
one line perpendicular to a given line at any point on the line. |
|
|
|
The perpendicular bisector... |
of a line is unique. |
|
|
|
If two angles are congruent, then... |
their bisectors separate these angles into four congruent angles. |
|
|
|
