Thanks for asking. I, too, am reluctant to lose this thread, for the same reason. There is so much that I could also say about their course assessment method, but I'll 'bite my tongue' and stay quiet. Yes, you have my permission.

]]>I have responded to them "I am awaiting permission from two forum members ... seems a shame as the student was very engaged in the process and learned a lot with members help, as would others visiting the page. There are likely to be many places on the internet (facebook, reddit, etc) where your students will find answers to previous questions, it seems easier to simply change your questions (even a little) every year."

Ignoring many arguments (and a heavy heart), it simply seems like a nice gesture to Compuhigh to remove it.

With your permission anonimnystefy and bob?

]]>Up to you where you post. I'll find it.

Bob

]]>I have another lesson I need help with. Would it be better to post here or make a new topic?

Earlier you said you would try answer D. That is what I would choose.

Bob

]]>I think you need to forget completely about the earlier question, where the answer was a rhombus. Start afresh with the four points.

If you plot them, look at the result and then join up, you get a rhombus. But I don't think that is what they expect you to do. I think I've met a similar Comp H question before like this. They expect you to join point one to point two, two to point three, three to point four, and finally back to point one again. If you do it like that you don't get a rhombus at all. You get what .... ????

The question doesn't make this clear but if rhombus was marked wrong then I recommend you go with ........ you tell me.

Bob

]]>Now seeing your image, I would go with D. But wouldn't it be considered as 4 right triangles that meet at a right angle?]]>

Congratulations for the 10.

For that problem I would not choose F.

]]>See below for my graph. What did you get?

Bob

Good news about the other work.

]]>(0,-1), (0,3), (1,1), (-1,1)

A A square

B Two acute angles that meet at the acute angles

CA triangle

D Two right triangles that meet at the right angles

E A rhombus

F Two obtuse triangles that meet at the hypotenuse

I would say for this one - F

By the way, my teacher replied for the previous math lesson and got 10.000!

]]>My new answer would be C.

Yes, that's what I think too.

Yes, I do. And thank you for the implied compliment.

Hi Bob,

I did #1 again.

First Set looks like a small triangle.

Second Set looks like a line segement.

Third Set looks like triangle.

My new answer would be C.
