here is the amath assignment that mrs tay has assigned for us to complete over the long weekend. it is due on
tuesday (04/07). everyone please submit without fail!
assignment 1 - coordinate geometry(amath tb, ex 7.2)
q3. The coordinates of the midpoint of the line joining A (p^2, p) and (q^2, q) are (5,1). Find the possible values of p and q.*
q5. Three if the vertices of a parallelogram ABCD are A(9,3), B(-2,1 ) and C(8,6).
a) write down the coordinates of the midpoint of Ac and hence, or otherwise, find the coordinates of the fourth vertex D
b) Prove that ABCD is a rhombus
(amath tb, ex 7.3)
q5. Given that the points A(1,-1), (t,2) and (t^2,t+3) are collinear, find the value of t.
(amath
tys, p42)
q8.
the diagram shows the trapezium
abcd in which
a is the point (1, 2),
b is (3, 8),
d is (5, 4), angle
abc = 90degrees. and
ab is parallel to
dc.
(i) find the coordinates of
c.
the point
e lies on
bd and is such that the area of triangle
cde is 1/4 of the area of triangle
cdb.
(ii) find the coordinates of
e.
the point
f is such that
cdfe is a parallelogram.
(iii) find the coordinates of
f and the area of the parallelogram
cdfe.
q10. point a, b and c have coordinates (1, 2), (-2, 6) and (9, 8) respectively.
(i) show that triangle abc is right-angled.
(ii) calculate the area of triangle abc.
in total there's 5 questions only for 3 days of "holiday". please make sure that you try your best to complete this assignment on your own and you must submit by tuesday, no excuses.
please pass the message around about this post to all those who still don't know.
