    Hey,

    I'm doing some revision on vectors and i can do all the other kinds of questions apart from one (probably simple) which i cant seem to work out how to do!

    Here it is: ABCDE if a regular pentagon. eg. (3 3) = a column vector.

    AB-> = (3 3)
    AC-> = (2 6)
    AD-> = (-2 6)
    AE-> = (-3 2)

    a) Draw the pentagon accurately.


    Please help its been bugging me.

    Thanks, Mike

    Are you sure you've typed this question right? In particular, the vectors? They don't all seem to be right to me. For example, the length of the side BC is sqrt(10), but the length of the side CD is 4. If ABCDE was a regular pentagon, they'd all be the same length.

    If i missed out regular would it be right? I might have misread it?

    If you missed out "regular", it would be a perfectly good question, but it wouldn't have an answer.
