Exemplars (from the NaCCA curriculum)
E.g.1 Deduce the triangle law of vector addition. ⃗ AB +BC ⃗ = ⃗ AC Where ABC are points in the 0xy plane. E.g.2 The vertices of a triangle are P(1,-3), Q(7,5) and R(-3,5) (i) Express PQ, ⃗ ⃗ QR , and PR ⃗ as column vectors. (ii) Show that triangle PQR is an isosceles. (iii) Find the equation of the linePR ⃗ . Eg3 Investigate the parallelogram law of vector addition. Eg.4P,Q,R,S is a parallelogram whose vertices are P (x ,y), Q (5,7), R(2,4) and S(1,3) (i) Find PQ, ⃗ andSR ⃗ hence find the values of x and y.
