Question

Stuck on a geometry quiz would anyone like to help me out?

Answer 1

what is it? ill try to help you, i'm only in Algebra though. :)

Answer 2

I'll try to help as well.

Answer 3

What do these terms below mean????
What is a counterexample for the conjecture?

What is the conclusion of the following conditional?

Another name for an if-then statement is a ____.
Every conditional has two parts. The part following if is the ____ . (1 point)
Write this statement as a conditional in if-then form:
Which conditional has the same truth value as its converse?
When a conditional and its converse are true, you can combine them as a true ____.
Write the two conditional statements that make up the following biconditional.


I didnt post the muliple choice options because I dont want the answers i just need you to explain what all these terms mean. Like conditional and biconditional and so on

Answer 4

Woah, this isn't the geometry u studied. dahell is this??

Answer 5

@andriod09 this is geometry

Answer 6

Thats what im saying, it makes NO sense to me. Lesson 3: Biconditionals and Definitions
Geometry Foundations A Unit 2: Reasoning and Proof<< thats my lesson though

Answer 7

So you learned what a Conditional Statement was then right?

Answer 8

@MathLegend im homeschooled, so something ik are different than what public school teaches.

Answer 9

Oh okay @andriod09

Answer 10

@BreannaRichele what does a Conditional statement consist of? Isn't it this: If I eat pizza, I will die.

(Made this up as an example. However, notice it uses If and Then which is a if then statement.)

Answer 11

If I eat pizza, then I will die.

Answer 12

My school is online. But anyway no none of this makes snese i have no idea what any of those are. i guess i didnt read in my book enough or something

Answer 13

Yes, in Geometry you must read.

Answer 14

Another name for an if-then statement is a ____. (Conditional Statement)

Answer 15

Now we call if the hypothesis and the then the conclusion

Answer 16

I am starting to learn that. oooh so if then is the same as a conditio

Answer 17

Right.

Answer 18

Every conditional has two parts. The part following if is the ____. (What is the answer to this one? Based off what I said)

Answer 19

then?

Answer 20

Good or the conclusion. So if I were you I would put 'Then (a.k.a. Conclusion)'

Answer 21

Write this statement as a conditional in if-then form:
(Was this one cut off? I don't see what it wants you to make into a conditional statement)

Answer 22

Write this statement as a conditional in if-then form:


All triangles have three sides.

(1 point)If a triangle has three sides, then all triangles have three sides.
If a figure has three sides, then it is not a triangle.
If a figure is a triangle, then all triangles have three sides.
If a figure is a triangle, then it has three sides.

Answer 23

Keep it in the order they give it to you. So what do they talk about first triangles or sides?

Answer 24

Triangles so woulld it be A...or D..or are both wrong? :/

Answer 25

It is out of A or D. Which one?

Answer 26

Be nice and simple.

Answer 27

A>?

Answer 28

You should have chosen...
If a figure is a triangle, then it has three sides.

Answer 29

You see how that is nice, short, and sweet just like the original statement?

Answer 30

yeah but isnt the first option short and sweet too? that doesnt make snese they are both saying the same thing i tohught.

Answer 31

If a triangle has three sides, then all triangles have three sides.

(This is talking about the sides first. We want triangles first.)

Answer 32

Sorry its taking a while this site is making my typing lag a little not sure why. But anyway yeah now i get it what is a biconditional then?

Answer 33

When a Conditional or If-Then statement is true... and its Converse.... is true then it is a Biconditional

Answer 34

and also
What is a counterexample for the conjecture?


Conjecture: All balls are spheres.

(1 point)a basketball
a football
a circle
a baseball
would that be football?

Answer 35

Conditional is: If p then q
Converse is: If q then p

Answer 36

Which conditional has the same truth value as its converse?
(Conditional)

Answer 37

When a conditional and its converse are true, you can combine them as a true ____.
(Biconditional)

Notice you combined so you got a Biconditional

Answer 38

Correct it would be a football.

Answer 39

okay what about this one
Rewrite the following statement as a conditional statement:


Apples grow on trees.

(1 point)If it grows on a tree, it is an apple.

If a fruit is an apple, then it grows on a tree.

Apples are a fruit if and only if they grow on a tree.

If it is not a fruit, then it is not an apple.
would it be C or B?

Answer 40

And this one looks like chinese to me
What is the conclusion of the following conditional?

A number is divisible by 3 if the sum of the digits of the number is divisible by 3.
(1 point)The number is odd.
The sum of the digits of the number is divisible by 3.
If the sum of the digits of a number is divisible by 3, then the number is divisible by 3.
The number is divisible by 3.

Answer 41

Well, a conditional statement is only If-Then... so it would be
If a fruit is an apple, then it grows on a tree.

Answer 42

Biconditionals use 'if and only if'

Answer 43

The number is divisble by 3.

Answer 44

so if a biconditional is an if anf if then would this one be D?
14. Rewrite the following definition as a biconditional:


Points that lie on the same line are collinear.

(1 point)If a point lies on a line, then it is collinear.

If a point lies on a line with another point, then the two points are collinear.

If two points are collinear, then they lie on the same line.

Points lie on the same line if and only if the points are collinear.

Answer 45

Yup.

Answer 46

yay. i dont understand this one either?
Which conditional has the same truth value as its converse? (1 point)If x = 7, then |x| = 7.
If a figure is a square, then it has four sides.
If x – 17 = 4, then x = 21.
If an angle has a measure of 80°, then it is acute.

i thought it was a but i think im wrong

Answer 47

Yes, A is definitely wrong.

Answer 48

then i dont get it

Answer 49

It can't be 'A' since a rhombus has four sides and a Rhombus is not a square.

Answer 50

It looks like there are two correct answers. They both check out as correct.

Answer 51

oh I see... the answer is 'B'

Answer 52

you can only pick on though.......

Answer 53

oh ok why

Answer 54

It can not be 'C' because the converse would be: If it is acute then the angle has a measure of 80 degrees

Answer 55

When in fact it would have a measure of any number between 0 and 90

Answer 56

Got it?

Answer 57

oh okay. I think i will get a good grade on this test now. thanks so much i actually understand it.

Answer 58

@BreannaRichele what were the answers to this test?
