Question

I need help with my math assignment pleasseeeee

Answer 1

where is it?

Answer 2

its the file attached.

Answer 3

That's an entire assignment! No one is going to help you unless you post the questions individually ;)

Answer 4

AAS
As 2 next angles and sides corresponding equal!

Answer 5

then answer one

Answer 6

:) It'll be easier for us to click on the image, so next time save as pic then post it!

Answer 7

ohp :3

Answer 8

Number 1 is AAS... Lol

Answer 9

Yea I got that :3

Answer 10

Number 4 is "angle B is congruent to angle E"
Sorry I'm skipping around the questions ahaha :P

Answer 11

Thank you and that's ok just do what you can :3

Answer 12

Alright, for question 2, let me rewrite the whole thing here

Answer 13

@mellieinc Sorry, most of the symbols aren't showing up on my computer for some reason D:

Answer 14

awww :(

Answer 15

Good, now let's go step by step;

Answer 16

This student first said: since AB=2 and DF=2, then AB must be congruent to DF, by the transitive property, right?

Answer 17

siiiii :3

Answer 18

So line 1, correct;

Answer 19

Line 2 states that angle A congruent to angle F, which are both 63 degrees, therefore, line 2 is also correct. Do you agree?

Answer 20

Great, now 3rd line is written to find the length of AC

A is at (1,2)
C is at (3,3)

They used the distance formula which is \[ d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]

In our case, \(x_1=1;~~y_1=2\) (Point A)
and
\(x_2=3;~~y_2=3\) (Point C)

Not too confusing here?

Answer 21

nope

Answer 22

Alright, now plug all value in the formula and let's solve;

\[ d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]
\(x_1=1;~~y_1=2\) (Point A)
\(x_2=3;~~y_2=3\) (Point C)
NOTE:
It could be
\(x_1=3;~~y_1=3\) (Point C)
\(x_2=1;~~y_2=2\) (Point A)

Like this, too.

\[ d=\sqrt{(1-3)^2+(2-3)^2}\]

Does that look like what he has?

Answer 23

so line 3 is equal?

Answer 24

So what I just wrote above correspond to what he wrote, exact?

Answer 25

yes

Answer 26

Good, so line 3 has no mistake, let's move to 4.

Answer 27

yayyy

Answer 28

Following the same process, we have to find the length EF:
\(x_1=5;~~y_1=3\) (Point F)
\(x_2=3;~~y_2=2\) (Point E)

\[d=\sqrt{(3-5)^2+(2-3)^2}\]

Does that correspond to what he wrote?

Answer 29

Actually, this has no mistake, unless they are very meticulous and want the angle to be in the middle, so \(\Delta \text{BAC}\cong\Delta \text{EFD}\)...
@AccessDenied

Answer 30

so its line 6?

Answer 31

Yeah, only thing I can find, need someone to check though.

@KingGeorge
@inkyvoyd

Answer 32

so line six is forsure the answer because the others are correct

Answer 33

Yeah, if we proceed by elimination, 6 would be the only option left

Answer 34

true

Answer 35

Ok, number 3 now. :)

Answer 36

yayyyy :)

Answer 37

Given these two triangles are congruent, tell me about your understanding of 'congruent triangles' and their properties? :)
