Answer 5

umm idk exactly

Answer 6

sorry i dont know

Answer 7

what grade math is this?

Answer 8

11th

Answer 9

oh ok..im in 8th grade

Answer 10

yeah im in 7th

Answer 11

Ok sorry i didn't know you guys were middleschoolers

Answer 12

its ok

Answer 13

lol its ok...im advanced in math but we havent learned this yet...so so sorry i couldnt help you

Answer 14

yeah sorry

Answer 15

@Comrad

Answer 16

You'd need two congruent angles

Answer 17

And two other congruent sides

Answer 18

ok... So what does that mean?

Answer 19

u see the little hash marks on the sides of the triangles?

Answer 20

A. O is the midpoint of PM.
B. MO≅OP
C. ON≅NO and MO≅OP
D. No additional information is needed to show that the triangles are congruent by SSS.

Answer 21

Those are the options

Answer 22

Well do you know what options we can cancel out?
(Unfortunately I can't just give you the answer)

Answer 23

D

Answer 24

Any ideas?

Answer 25

D definatley isnt it

Answer 26

Right. Ok, let's take a look at the name. It's called the SSS Postulate (Side, Side Side) So that means that we're looking at the congruency of sides and not angles, or any thing else. SO what else could we rule out?

Answer 27

@brooke_ivy99 Soo...

Answer 28

wait is the answer B or C?

Answer 29

Ok, good, you've ruled out C! That's a step!

Answer 30

Ok, so now, let's take a look back at the name. How many CONGRUENT sides does it mention in the name of the postulate?

Answer 31

No. So A is the answer?

Answer 32

No. We ruled out A and D remember. A refers to the midpoint. Look We need 3 congruent sides. We already have 1 congruent side based on the graph, which option has two more congruent sides?

Answer 33

I thought we ruled out C and D sorry

Answer 34

My bad, please forgive me. I've made a mistake. We ruled out A and D!

Answer 35

Oh ok. SO its up to B and C
And between the two I choose B

Answer 36

Does that answer have 2 sets of congruent sides?

Answer 37

Under the SSS Postulate, we need to have three sets of congruent sides. We have MN and NP due to the graph. B will give us MO and OP. Is that 3 sets of congruent sides?

Answer 38

So...

Answer 39

OH ok so it cant be B it has to be C

Answer 40

Correct! Can you explain why It is correct!

Answer 41

Because with the SSS postulate we have to have 3 congruent sides

Could you help me with another question?

Answer 42

Correct!!!! And sure, open up a new question, close this one!

Answer 43

Ok :)
