Question

Can anybody please help me with this proof?

Answer 1

Is A the correct answer for question 2?

Answer 2

The bottom part of this page has different kinds of equal or opposite angle pairs, that might help. http://www.mathsisfun.com/geometry/alternate-interior-angles.html

I agree with your #2.

Answer 3

@theEric Could you help me with the other questions please?

Answer 4

I'll have to be going soon, but I can take a look! Post it!

Answer 5

here @theEric. THANK you so much!

Answer 6

Going through the options for that first one, which are true?

Answer 7

I think B?

Answer 8

More importantly, what can you prove true at that point. I agree, again! And for what reason? (Next question)

Answer 9

Side angle side?

Answer 10

I agree again!

Answer 11

Then is C correct for question number 5?

Answer 12

For the next one, you're looking for what you know from those two triangles being congruent. I agree, again!

Answer 13

thanks a lot. There is two more questions, could you help?

Answer 14

for question number 10 is A correct?

Answer 15

It seems like you know this! Here was my hint: the last step assumes ..

I agree again! Now, why?

Answer 16

for this one I am confused... I was thinking SAS?

Answer 17

Well, you have to go through and see what you've established to be true!Focus on those end triangles that we say are congruent. Why can we say that? SAS means the equal angle is between two equal sides. We don't see that.

Answer 18

side side side? Sorry I am so confused about this one

Answer 19

But you don't know all the sides! You're getting closer by process of elimination!

Answer 20

hmm, it can't be all side because there is one angle present, the right angle

Answer 21

@theEric is it angle angle side?

Answer 22

there is only one angle, so it would be SAS (side angle side)

Answer 23

Well, you don't know two angles, so it can't be!

Answer 24

Now what's left?

Answer 25

But I suggested SAS you said that it wasnt correct. So HL is the right answer or what?

Answer 26

HL is hypotenuse-leg. It works for right triangles only.

Answer 27

SO ITS side angle side???? But you said it was wrong!!!! so confused right now

Answer 28

The only option that can apply is HL

Answer 29

Ahhh thanks a lot!! for everything :) you've got so much patience!!!

Answer 30

They \(are\) right triangles, that was proven earlier. The outermost edges were given to be the same length (hypotenuse). The inside edges of the triangles were proven to be the same earlier, too.

Answer 31

Haha, thanks. Take care! Good luck with the course!

Answer 32

Thank you so much!!!!!
