17
Q

enumeration, enumerate theses postulates from 1-6

_____2 points determine a line
_______through any 3 non colinear points there is one plane
_______if there are 2 points that lie in a plane a line would be joining them
______a plane contains atleast 3 non colinear points
_______through any 2 points there is exactly one line
______if 2 plane intersect then their intersection would be a line

A

1- 2 points determine a line
4- through any 3 non colinear points there is one plane
5- if there are 2 points that lie in a plane a line would be joining them
2- a plane contains atleast 3 non colinear points
3- through any 2 points there is exactly one line
6-if 2 plane intersect then their intersection would be a line

18
Q

what is the theorem

if 2 lines intersect they intersect in exactly one 1 point

19
Q

what is this theorem?

if 2 lines interesect there is exactly one plane that contains both

20
Q

what is this theorem?

if a point lies out of a line then there is a plane that contains them both

21
Q

is a compound statement of the form “if p then Q”

also called an if then statement

A

conditional statement

22
Q

p is the what qand it begins with ifj?

23
Q

what is p?

usually begins with then

24
Q

is a tentative assumption made in order to draw out logical consequences

25
is the necessary consequence of one or more propositions
conclusion
26
formed by interchanging the conclusion and the hypothesis( if q then p)
converse
27
formed by interchanging the hypothesis and the conclusion and negating them both( if not q then not p)
contrapositive
28
formed by negating both the hypothesis and conclusion(if not p then not q)
inverse
