general postulates and theorems (Chp. 2)

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.
        Help!  

hypothesis
conclusion
Through any two points   there is exactly one line  
🗑
Through any three points not on the same line   there is exactly one plane  
🗑
A line contains at least   two points  
🗑
A plane contains at least three points   not on the same line  
🗑
If two points lie in a plane   then the entire line containing those points lies in that plane  
🗑
If two lines intersect   then their intersection is exactly one point  
🗑
If two planes intersect   then their intersection is a line  
🗑
If M is the midpoint of line AB then   line AM is congruent to line MB  
🗑
The points on any line or line segment can be paired with real numbers so that given any two points A and B on a line, A corresponds to   zero, and B corresponds to a positive real number  
🗑
If B is between A and C   then AB+ BC= AC  
🗑
Congruence of segments is   reflexive, symmetric, and transitive  
🗑
Given the ray AB and a number r between 0 and 180, there is exactly one ray with endpoint A, extending   on either side of ray AB, such that the measure of the angle formed is r  
🗑
If R is in the interior of angle PQS, then the measure of angle PQR plus the measure of angle RQS equals the measure of angle PQS. If the measure of angle PQR plus the measure of angle RQS will equal the measure of angle PQS, then R is the interior of   angle PQS  
🗑
If two angles form a linear pair, then   they are supplementary angles  
🗑
If the noncommon sides of two adjacent angles form a right angle, then   the angles are complementary angles  
🗑
Congruence of angles is reflexive, symmetric, and   transitive  
🗑
Angles supplementary to the same angle or to congruent angles are   congruent  
🗑
Angles complementary to the same angle or to congruent angles are   congruent  
🗑
If two angles are verticle angles, then they are   congruent  
🗑
Perpendicular lines intersect to form four   right angles  
🗑
All right angles are   congruent  
🗑
Perpendicular lines form   congruent adjacent angles  
🗑
If two angles are congruent and supplementary, then   each angle is a right angle  
🗑
If two congruent angles form a linear pair, then   they are right angles  
🗑
Conclusion   In a conditional statement, the statement that immediately follows the word "then".  
🗑
Converse   The statement formed by exchanging the hypothesis and conclusion of a conditional statement.  
🗑
Hypothesis   In a conditional statement, the statement that immediately follows the word "if".  
🗑
Inverse   The statement formed by negating both the hypothesis and conclusion of a conditional statement.  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
