Question

Properties, Proofs, All that nasty stuff :( Help please...

Answer 1

If two angles are vertical, then they are congruent. If two angles are congruent, then they have the same measure. the law of syllogism allows us to draw what conclusions?
10If two angles are congruent, they are vertical
2)If<abc=<def, then they are vertical
3)If two angles are vertical, then they have the same measure.
4)If two angles have the same measure, they are vertical.

Answer 2

@jigglypuff314 help?

Answer 3

some angles can be not vertical angles and still be vertical.
so that Disproves 1 and 4
and you don't know what "<abc" and "<def" are, so 2 Can't be right...
so that leaves...

Answer 4

Number 1?

Answer 5

congruent angles don't have to be vertical angles
like how a rectangle doesn't have to be a square
so not 1 :)

Answer 6

3 lol sorry

Answer 7

yep! :)

Answer 8

What is the conclusion to the statement "if two lines are skew, then they do not lie in the same plane."

Answer 9

The "if" part of a conditional statement is called the hypothesis, and the "then" part is called the conclusion.

Answer 10

Thanks

Answer 11

yw :)

Answer 12

so they do not lie in the same place would be the conclusion?

Answer 13

yep :)

Answer 14

alrigghhtu

Answer 15

if p: two lines intersect and q: they share a common point, write ~p->~q as a conditional statement.

Answer 16

@Chooch146 any idea?

Answer 17

this link might help http://www.mathplanet.com/education/geometry/proof/if-then-statement
(I have done geometry in a while >,< )

Answer 18

so... "If two lines do not intersect, then that do not have a common point"
