Postulate 1 |
Only one straight line can be drawn through two points; two points determine a straight line |
Straight line |
|
Postulate 2 |
A straight line is the shortest line connecting two points in a plane |
Shortest line |
|
Postulate 3 |
A line segment can be bisected at only one point |
Bisect |
|
Postulate 4 |
Two lines in the same plane either intersect or are parallel. If two lines intersect, four angles are formed at the point of intersection. |
Intersect or parallel |
|
Postulate 5 |
An angle has only one bisector |
Bisector |
|
Postulate 6 |
All straight angles are congruent |
Straight angles |
|
Postulate 7 |
All right angles are congruent |
Right angles |
|
Postulate 8 |
In a plane, only one line can be drawn through a point perpendicular to a line |
Perpendicular |
|
Postulate 9 |
If one line meets another line the adjacent angles formed are always supplementary |
Adjacent angles |
|
Postulate 10 |
Angles that are complements of the same angle, or congruent angles, are congruent |
|
|
Postulate 11 |
Angles that are supplements of the same angle, or congruent angles, are congruent |
|
|
Postulate 12 |
Vertical angles are congruent |
Vertical angles |
|
Postulate 13 |
The sum of the measures of the angles around a common vertex on one side of a line is 180 |
Sum |
|
Postulate 14 |
If three sides of one triangle are congruent to three sides on another triangle the triangles are congruent |
SSS postulate |
|
Postulate 15 |
If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle the triangles are congruent |
SAS postulate |
|
Postulate 16 |
If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle the triangles are congruent |
ASA postulate |
