Answer 2

omg thank you can you tell me if im right?

Answer 3

you're welcomeeee :D!!
And sure, type up what you think the answers are and i'll tell you if you need to fix any :)

Answer 4

omg okay thanks!

Answer 5

ok for the first one i got SAS

Answer 6

one i got ASA

Answer 7

i mean second oops

Answer 8

thrid one i got sas

Answer 9

and fourth one i got ASA

Answer 10

are those correct??

Answer 11

1st one - SAS (correct)
2nd one- ASA (correct)
3rd one - SAS (incorrect)
4th one - ASA (incorrect)
good try :)
just re-attempt the 3rd and 4th one

Answer 12

ok thanks! give me a sec haha

Answer 13

okey dokeeyyyy

Answer 14

is the 3rd one sss?

Answer 15

yess :D!

Answer 16

and 4th asa?

Answer 17

yay!!!!!!!

Answer 18

4th one.. you said ASA the first time and that was incorrect :)
first look at the triangle and tell me if it has 2 sides and 1 angle that match or 1 side and 2 angles that match

Answer 19

wait oops i meant to say sas

Answer 20

yyeeees :D excellent :)

Answer 21

omg yay thanks! i have another question can you help me on it?

Answer 22

you're welcomee :)
sure, i can try to help though my geometry isn't very strong xD

Answer 23

Use the diagram below. Tell why each statement is true.
∠A ≅ ∠ C
∠AXB ≅ ∠CXD
∆ABX ≅ ∆CDX

Answer 24

oh dear.. I can do this question, but i'm not good (horrible) at explaining it xD
So i'm sorry! But if you close this question and post it as a new post, someone else will SURELY help you step by step :))

Answer 25

hmmm idk you you try to explain it because if i see the answer maybe i can understand why that is the answer?

Answer 26

okay i can try but idk how well this will end LOL.

So firstly, we want to state why angle A is CONGRUENT (equal) to angle C.
Hint: we are given that \[AB // CD\] , so why would <A = <C ?

Answer 27

is it the reflexive property??

Answer 28

not quiteee. Do you know about alternate angles, corresponding angles and co-interior angles? :)

Answer 29

somewhat haha

Answer 30

okay, well between two parallel lines:
these angles will be EQUAL because they are alternate angles.

Answer 31

so if you look at your diagram, what would your reason be for why <A = <C ?

Answer 32

if lines are paraellel then alt interior angles are congruent?

Answer 33

yeeeeeeeeeeeeeees! :D

Answer 34

omg yay!!!!!!

Answer 35

ok now what about the other two questions??

Answer 36

what would be your reasoning for why these two angles are equal? :)
