Question

What additional information is needed to prove the triangles are congruent by HL?

Answer 1

I think A or C.

Answer 2

you're alredy given that the hypotenuses are congruent... if you're proving by HL, the H means hypotenuse. what does the L mean?

Answer 3

Okay.

Answer 4

LEg

Answer 5

so which choice gives 2 corresponding legs as congruent? certainly not A or C!

Answer 6

Ah, I see!

Answer 7

I was mistakened, I suppose.

Answer 8

D?

Answer 9

are you asking or telling?

Answer 10

Both, I guess.

Answer 11

be confident and prove to yourself that it has to be right. even if you're wrong you'll learn because you'll be wondering why you're logic was wrong, notice your error and then you'll correct your thinking, meaning you learn!

Answer 12

also, it helps to mark on the drawing, then it becomes much clearer!

Answer 13

So I'm wrong?

Answer 14

that's not what i said

Answer 15

So I'm not wrong?

Answer 16

He didn't say that either :P

Answer 17

i didn't say that either. prove to yourself why that choice is either correct or incorrect

Answer 18

I'm not sure how to do that. please help?

Answer 19

like i said, if your choice is D, mark up your drawing and see if that allows you to prove by HL.

Answer 20

I don't get how to do that

Answer 21

can I prove these 2 triangles congruent by HL? In other words, do I have some way of knowing that I have 2 right triangles, with congruent hypotenuses and a pair of corresponding legs which are congruent?
