Hi,

Thanks for sharing the MD method.[/quote]Hi,
Thanks! Although I see this is labelled as P4 math, can actually find this question in one of the P3 math paper. Now I understand how to do using MD.

Hi,
Similar questions (handshakes, chess game etc) were taught in my child's school in P2! I agree should be P3/4 standard! :faint:

Hi Tianzhu,
Very curious, what do you use to produce all these fantastic diagrams/pics to explain?
Impressive :salute: How much time do you need to typically come up with one?

Hi Ksi,
yes, I do know that can use ppt. Just that I'm really amazed that Tianzhu will take the effort to present it really nicely with explanation. Her response time is rather fast too Finally, appreciate her efforts too.

Tianzhu is a daddy if that explains further...kekeke sorry I am not being sexist here cos I am a mummy.

Actually ppt is easy to use for people who are familiar and templates can be built up, I am saying it as one who is a veteran user of this tool.

This is a P4 question.


Draw a straight line through the point D. Then, construct another line perpendicular to the line that you have drawn and it has to cut through point E.

Below is the child's answer. My question is the second line touches point E and it crosses the straight line through point D. Would this answer be take as correct or incorrect?
