Question

Dilate the given triangle with amagnitude of 3.Geometric Transformations (Matrices)

Answer 1

In order to dilate the triangle by a factor of 3, we multiply each component of the Matrix by three. Doing this gives us

`\begin{bmatrix}{3} & {6} & {3} \\ {-3} & {3} & {3} \\ {} & & {}\end{bmatrix}\cdot3=\textcolor{#FF7968}{\begin{bmatrix}{9} & {18} & {9} \\ {-9} & {9} & {9} \\ {} & {} & {}\end{bmatrix}}`

The matrix on the right is our answer.
