    'All rhombuses are similar' I got this wrong admittedly. My only guess is even if they have the same (proportions ) for the sides, you can get instances where the corresponding angles are different. I've drawn a diagram below: \angle \ ABD $ could be different to $ \angle EFH

    HSC 2017 Business Studies Marathon

    Decided to open up a Business Studies Marathon for any current or former HSC students to discuss any content related to this subject. I've done some accounting and finance units before but hardly remember any of it as I did it a long time ago. Thought it would be good to brush up a few...

    Hence, why your correct when the question came 'All rectangles are similar'-----> FALSE (in the textbook) Again, before today I would have said TRUE. I do understand now that you have to look at the aspect ratio (long sides v short sides of both shapes)

    Interesting little fact from that wikipedia link: "For example, all circles are similar to each other, all squares are similar to each other, and all equilateral triangles are similar to each other. On the other hand, ellipses are not all similar to each other, rectangles are not all similar to...

    Year 9-10 Maths Discussion & Resources

    I came across this question in the Cambridge year 10 maths book and it got me thinking this early morning. This chapter was part of the Geometrical figures and circle geometry. (I haven't looked at the answer yet) Q. Are these statements true or false? " All circles are similar" I think...

    What other Circle Geometry programs are there ? Or ones that the NSW curriculum encourage students to use? Geogebra is one. Efofex is one that is used in WA (but I never touched much on that subject in the past), so rarely touched it Are there maybe other ones that are used?

    Just a bit of a left field question, do the high schools in NSW teach the students to spend much time on drawing out Circles , in circle geometry? Personally, think it would be a great learning tool in learning Geogebra or the equivalent circle geometry software and enhancing that learning at...

    Fourth year law student - ask me anything!

    Also no disrespect to Allens- I have never heard of them (but based on what I have read I'm not sure if it's a company that I would want to work for-they do seem a tad elitist) but do they have any links with UWA law by any chance? Not sure but I didn't have too many friends at UWA law at my...

    Fourth year law student - ask me anything!

    I wrote this on the Whirlpool forum and I'll post it here on the BoredofStudies. I have no jealousy or animosity towards people that achieve high ATAR's but the recruitment process factoring into account ATAR is a bit of a joke if you tell me. I must admit I had a fairly average ATAR coming...

    Re: International Baccalaureate Marathon Was going through worked example from Cambridge tonight and there was a mistake in the working out for part (c), vector BC should be -2-k. Small mistake but its important that I point it out to all IBers in 2017:

    IB Maths Marathon

    Re: International Baccalaureate Marathon ^^ Building on from what I have said, if the vectors are meeting in opposite directions, I need to reverse one of them so that either they meet together or leaving the same point at the one time.
