Question

suppose triangle bca is congruent to triangle ecd.which is not necessarily true?
a)line ba is congruent to ed
b) 12 years ago

Answer 1

Do u have a diagram?

Answer 2

i think its D

Answer 3

every answer is tru execpt D

Answer 4

It could be c or d

Answer 5

i think D has more sense because both triangles might be equilateral

Answer 6

makes*

Answer 7

Can u draw the diagram? @maria_amd just click draw under the reply box

Answer 8

its D

Answer 9

Is this all u have for ur diagram?

Answer 10

@nikato yea.

Answer 11

you can solve the question with tht

Answer 12

its D because <bcd is not congruent to <dce

Answer 13

But can also be C becuz u don't know if those 2 sides r equal

Answer 14

im pretty sure there equilateral

Answer 15

triangle bca is congruent to tri. ecd.
so the angles must also be congruent?
so maybe it isn't d?

Answer 16

it is D because >bcd is an obtuse triangle and >dce is an equilateral which means all the angles are acute

Answer 17

so they are not congruent

Answer 18

so the answer is D

Answer 19

that makes more sense, thank you.

Answer 20

no prob
:)

Answer 21

:).

Answer 22

But could be c becuz BE and AD could be perpendicular

Answer 23

but C asks you for EC CD

Answer 24

and they are congruent

Answer 25

U can't prove EC=CD with what's given

Answer 26

because it is an equlateral triangle

Answer 27

Ur just assuming

Answer 28

yes because triangle bca and dce are congruent -_-

Answer 29

Yes, I agree they r congruent, but that doesn't mean those triangles are equilateral

Answer 30

measure them

Answer 31

That's true.

Answer 32

Geometry 101: diagrams are never drawn to scale. U can't trust them. Only trust what's labeled

Answer 33

but even if they are not equilateral all the sides from triangle bca are equal to ecd

Answer 34

measure it? ive been told not to measure, and to trust it.

Answer 35

i mean to measure all the sides from the triangle

Answer 36

but the diagram isn't drawn to scale.

Answer 37

Yes, all the sides of one of the triangle is congruent to the other, but EC and CD are sides of the same triangle

Answer 38

but are they congruent?

Answer 39

SO IT'S C!!!!,

Answer 40

U don't know EC and CD are congruent

Answer 41

you think its C an i think its D

Answer 42

lets just leave it like tht bro

Answer 43

Okay. I'm fine with that^

Answer 44

lol

Answer 45

Peace. Maria can decide for herself based on what we argued then

Answer 46

im not._. this is a take home test.

Answer 47

haha

Answer 48

chooose one and will see

Answer 49

choose which ever you think its right

Answer 50

at first i thought it was d and now i feel like its c.

Answer 51

then choose C its ur choice

Answer 52

and even i don't think they will giv you a fake diagram because then you wouldn't know how the triangle looks

Answer 53

Yea, what ever u choose based on what u know already. It's fine, just let ur heart and mind decide

Answer 54

well i measured it and they are both equilateral.

Answer 55

those were some wise words

Answer 56

so i'm guessing it's d.

Answer 57

i still think it is D because now we know they are equilateral and with that we know C is correct so the only fake one is D

Answer 58

yea, thanks for your help :).

Answer 59

ur welcome

Answer 60

Awwwwww. So close. But u should tell us what the correct is when u find out

Answer 61

will do to both of you:).

Answer 62

now that i looked at it closely it might be C

Answer 63

Does D refer to the angles or the triangle?

Answer 64

angles

Answer 65

then i think its C because in the triangle bce and ecd have the same angles but it is the lines that are not the same so it is C

Answer 66

i think @nikato is right

Answer 67

@nikato you're right.

Answer 68

Go with C

Answer 69

i apologize @nikato

Answer 70

Oh yea!
I think u all just learned a very valuable lesson.
NEVER trust the diagram given, like the measuring part

Answer 71

haha
