  • Draw or state the transformed triangle after applying the matrix to all vertices.

8.L Vectors and matrices question 1

[Maximum number: 3]
Figure for Question 8.L Vectors and matrices question 1 — Edexcel IGCSE Math B

The points with coordinates (1,2),(1,5) and (3,2) are the vertices of triangle A.

Question (a)

(a)

Hence, on the grid, draw and label triangle C.

Question (b)

(b)
Figure for Question (b) — Edexcel IGCSE Math B

The single transformation that maps triangle B onto triangle C is represented by the matrix N.

State, giving a reason, the matrix N2N^2.

Only use this grid if you need to redraw your triangles.
