Question

In triangle PQU and triangle PRT, why would line PQ and line PR be congruent? I can't remember what the theorem is called. The picture will be in the comments.

Answer 1

I trying to find the theorem hold up .

Answer 2

we would need some more info before we can prove segment PQ and segment PR are congruent....

Answer 3

do we know if the two triangles are congruent ... or can we prove it using the other angles or sides?

Answer 4

All the problem is asking me to do is identify any common sides or angles of the two triangles. I have everything else figured out I just need to remember what that theorem is called.

Answer 5

Let's recap first:
Do you have a list of theorems or theorems you can remember ?

Answer 6

This may or may not help:

Answer 7

I already know all of that.

Answer 8

Hold on to your shoes! So the problem is just like that all sides no angles or jesus ?
No!!!!

Answer 9

Great now I have to find things.....

Answer 10

I know why all the other angles and lines are congruent, I just need to figure out why line PQ and PR are congruent.

Answer 11

Wait a sec..... that's it your holding out on us man you need tell almost how you found out the other stuff for us to help you

Answer 12

corresponding sides of congruent triangles ?

Answer 13

not ALL of the stuff but more info like what Pax said

Answer 14

I think I'm just stupid... man I don't even know.. I know that angle P is congruent to angle P by reflexive property, I think line QU is congruent to line RT by mid-segment theorem (not completely sure on that one) and that's it. There's no givens or anything. The question is "Identify any common sides or angles of triangle PQU and triangle PRT."

Answer 15

You are not stupid if anything its our fault for confusing we just want to HELP you not SHAME you

Answer 16

Oh I know that. I'm not offended or anything. I'm just saying that I'm not even sure if line PQ is congruent to line PR. It was more like a shout into the void hoping my instinct was right. I appreciate you trying to help me. Sorry if I confused you and made such a big fuss over nothing.

Answer 17

Jelly you are awesome always go with your first instinct, and also I was horrible at geometry(at first) . But I confused you by asking you the wrong questions. Sorry! Listen we will get this no matter always believe yourself, even if you don't just keep telling yourself to believe you. I am not saying everyone is perfect or anything because people do make mistakes(Believe me! I'm in the same boat). However, afraid to make those mistakes, that is how we learn. Don't be afraid to keep moving forward no how hard you fail!

Answer 18

Stupid computer always ugh!!

Answer 19

Thanks! And don't worry about it. I failed geometry my first semester last year. That's why I'm retaking it online.

Answer 20

Geometry huh that's it! THe mid-segment theorem proves QU to RT right ?

Answer 21

RT is a side of PRT right ? and PQU is a side of QU right ? So couldn't we us the side-side-side theorem to prove it true ?

Answer 22

Using the transitive property ? It's only a guess

Answer 23

and the symmetric property of course !

Answer 24

Answer 25

It's on here!

Answer 26

Wait so would line PQ be congruent to line PR by symmetric property? I'm still a little confused by the definitions. I would know if there was examples.

Answer 27

Let's say that RT is a right ?

Answer 28

RT is A
TR is B
PR is C

Answer 29

RT = QU
so
A = QU
because you proved that correctly I know

Answer 30

SO therefore we have proved that one of the sides of the triangle is equal to another

Answer 31

Okay thank you for all of your help!

Answer 32

No problem!! Helping is good do you understand it well enough ?

Answer 33

Yeah I think I do.

Answer 34

ALright have fun with life and remember don't hate math! Hate the ones who make it boring

Answer 35

I actually love math.. that is until I don't understand it lol. Thanks again!

Answer 36

Then remember mistakes are thy friends,they teach, however yielding is thy enemy, they destroy.

Answer 37

Bye-Bye
