Question

Find the value of x and y so that trangle ABC is congruent to triangle DEF by HL.

Answer 1

Do you have an idea on how to begin?

Answer 2

Yes i have an idea let me write it out

Answer 3

Okay. We need to know which sides correspond so that their algebraic lengths can be set equal.

Answer 4

Can you write out the steps like baby steps im having a hard time kinda making out how to do this like the last problem :(

Answer 5

I really want to learn this and get it down pat if you dont mind teaching me

Answer 6

I will help you with that but I'm still trying to understand how to do that and be within the new guidelines here at OS-Math. There's a no answer only policy. Did you see it? I'm not saying you want only the answers. I'm saying I'm trying to figure out how to proceed.

Answer 7

Let's just do it and if I say too much, then I'll be told.

Answer 8

Question: What does the H mean in HL Postulate?

Answer 9

Work with me. I have already worked out the problem.

Answer 10

Ok sorry mom asked me to get the dishes im back

Answer 11

No problem.

Answer 12

Here's where we are: What does the H mean in HL Postulate? Or, what does H stand for?

Answer 13

hypotenuse?

Answer 14

for hypotenuse leg

Answer 15

I think I got it

Answer 16

hold on let me write it out

Answer 17

Okay, Post your work and let's compare.

I'll say that side AB corresponds to side DE.
That would make 5x + 2 = 8x - 10.
So, I have to solve that for x.

Your Task: What is the equation to solve for y?

Answer 18

That's what I got for x. And, now y.

Answer 19

So its B x = 4, Y = 5

Answer 20

Yes, HL Postulate is for right triangles and states that if the hypotenuse and leg of one right triangle are congruent to the corresponding parts of another right triangle, then the triangles are congruent. So, by computing values of x to make that happen, the triangles are congruent by HL.

Answer 21

How's that?

Answer 22

Thats great :) ps so whats with the new guidelines, i missed them

Answer 26

Hmm from what i read There saying show the way to how you solved the problem don't just give answer and if they need it help them and no sniping

Answer 27

Its ok to give the answer as long as you try and teach them how you got it... there also saying give it last because they will just move on if you give the answer right away

Answer 28

Nah my Cpu is at 100f when I play bf3 its 125f and when i idle its 90 so idk no to hot

Answer 29

dont worry all computers have a safty switch that will turn off the computer if it gets to hot check out a program called "core temp

Answer 30

what chat thread
